Unit 2, Lesson 11# Writing Equations for Lines

Open Up Resources 35 min(s)

Introduce the idea that every point on a line has a property in common, namely the quotient obtained by considering a slope triangle containing that point. Let's explore the relationship between points on a line and the slope of the line. Learning targets: students can decide whether a point is on a line by finding quotients of horizontal and vertical distances. The previous lesson introduces the idea of slope for a line.
