Unit 2, Lesson 12# Using Equations for Lines

Open Up Resources 35 min(s)

Find an equation for a line with a positive slope in the coordinate plane using knowledge of similar triangles. Recognize that a line can be built by taking all of the dilations of a single point which use another point on the line as a center. Let's write equations for lines. Learning targets: students can find an equation for a line and use that to decide which points are on that line.
