# Linear functions slope-intercept form write an equation in point

We can move the x term to the left side by adding 2x to both sides. We have seen that we can transform slope-intercept form equations into standard form equations. Summary Students learn about four forms of equations: They graph and complete problem sets for each, converting from one form of equation to another, and learning the benefits and uses of each. Engineering Connection The idea of slope as the rate of change is essential to understanding how lines are graphed.

Engineers must be able to create and also understand graphs that can explain sets of data. Mechanical engineers read and understand graphs that show displacement, velocity and acceleration to then analyze data from testing sites to learn how to design their products such as cars and airplanes to be more efficient and safe.

In journal questions of the summary assessment, students think as engineers, considering the meaning of key data points and the purpose of using lines to model data. Pre-Req Knowledge Students must understand that linear equations have other equivalent forms that may be determined just by rearranging the equation using properties of equality.

## Slope Intercept Form

They must also know how to graph points on a coordinate plane and determine the slope of a line. Prior knowledge of intercepts is also recommended.

Learning Objectives After this lesson, students should be able to: Distinguish between different forms of equations, including direct variation, slope-intercept form, standard form and point-slope form.

Explain what is meant by the term equivalent equations. Convert from one form of equation to another. Tell when each form is useful and how to graph using each form. Use the slope of a parallel or perpendicular line along with a point on the line to write the equation of the line in any of the three main forms.

Students learn how to quickly and efficiently interpret graphs, which are used for everyday purposes as well as engineering analysis. The focus is on students becoming able to clearly describe linear relationships by using the language of slope and the rate of change between variables.

High School Lesson A Tale of Friction High school students learn how engineers mathematically design roller coaster paths using the approach that a curved path can be approximated by a sequence of many short inclines. They apply basic calculus and the work-energy theorem for non-conservative forces to quantify the friction along a curve High School Lesson All about Linear Programming Students learn about linear programming also called linear optimization to solve engineering design problems.

They apply this information to solve two practice engineering design problems related to optimizing materials and cost by graphing inequalities, determining coordinates and equations from Slope Students learn about an important characteristic of lines: Students get an explanation of when and how these different types of slope occur.

## Linear function - Simple English Wikipedia, the free encyclopedia

In the ASN, standards are hierarchically structured: Common Core State Standards - Math Decide whether two quantities are in a proportional relationship, e. View more aligned curriculum Do you agree with this alignment? Yes No Thanks for your feedback!

Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two x, y values, including reading these from a table or from a graph.

Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.Menu Algebra 1 / Visualizing linear functions / The slope-intercept form of a linear equation.

Our second point is a solution to the equation i.e.

Write the ordered pair for each point. A y O x B A D C E F B C D E F Equations of Linear Functions Make this Foldable to help Words The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. (0, b) O y x. Write the equation of the line parallel or perpendicular to the given line that passes through the given point. Give your answer in point-slope form and slope-intercept form. 11] Parallel to =− 4. Straight-Line Equations: Slope-Intercept Form. Slope-Intercept Form Point-Slope Form Parallel, Perpendicular Lines. Purplemath. Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them.

the line we drew is correct. The slope-intercept form of a linear equation; About Mathplanet; Formulating linear equations. Algebra 1; Formulating linear equations.

An alternate form of a linear function which is probably very familiar to most readers is the slope-intercept form of a line. Slope Intercept Form of a Line If the linear function $$f$$ has slope $$m$$ and $$y$$-intercept $$b\text{,}$$ then the slope-intercept form of the equation of a line is given by.

## Worksheet: Equation of a Line in Slope Intercept Form

In Example 2 we converted an equation in standard form to slope-intercept form. Any linear equation in standard form withB 0 can be written in slope-intercept form by solving for y.

To write an equation in point-slope form, given a graph of that equation, first determine the slope by picking two points. Then pick any point on the line and write it as an ordered pair (h, k).

Students learn about four forms of equations: direct variation, slope-intercept form, standard form and point-slope form. They graph and complete problem sets for each, converting from one form of equation to another, and learning the benefits and uses of each. Page 1 of 2 Quick Graphs of Linear Equations 83 Graphing with the Slope-Intercept Form Graph y= 3 4 xº 2.

SOLUTION The equation is already in slope-intercept form. The y-intercept is º2, so plot the point (0, º2) where the line crosses the y-axis. The slope is 3 4, so plot a second point on the line by moving 4 units to the.
