5.2 Defining Slope

Lesson Essential Question: Can you calculate slope using rise over run and the formula for finding slope?

"Bellringer"

Given the equation 4x + y = 36

(8 , ?) Find y.

a) y = 3b) y = 4c) y = 5d) y = 6

What word(s) come to mind when you hear the word SLOPE?

_____________________ is the ratio of vertical rise to horizontal run.

Formula for Slope:

y2 - y1

x2 - x1
