Question

These points are linear.
Find the slope.

x -2 -1 0 1 2
y -7 0 7 14 21

Answer 1

7

Explanation:

use the equation y2 - y1/ x2 - x1 to find the slope

-7 - 0/-2 - (-1)

-7/-1
7

y = 7x + b

if you want to check we have to find the y-intercept

(i can also show how to find it if you want :D)
