This is the second Powerpoint lesson I use to teach my students to Write the Equations of Lines. I have divided the topic into four lessons:
1. Writing Equations of Lines: Day 1 This lesson 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.
Common Core Standard:
Build a function that models a relationship between two quantities.
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.
