This is the Powerpoint lesson that I use to first introduce my students to Writing Equations of Lines. I have divided the topic into four lessons:
1. This lesson which shows how to write the equation given the slope and the y-intercept, and how to write the equation given a graph. It also shows the slope-intercept form and standard form of the equation.
2. Writing Equations of Lines: Day 2
which shows how to write the equation given the slope and a point contained in the line, and how to write the equation given two points on the line.
3. Writing Equations of Lines that are Parallel or Perpendicular to a given line.
4. A review of writing the equations and graphing the lines with the information given.

F-BF 1. Write a function that describes a relationship between two quantities.
Previous California Standard for Algebra 1:
7.0 Students verify that a point lies on a line, given an equation of the line. Students are able to derive linear equations by using the point-slope formula.
8.0 Students understand the concepts of parallel lines and perpendicular lines and how those slopes are related. Students are able to find the equation of a line perpendicular to a given line that passes through a given point.
