Question

What is the rate of change for the following? (4,5) (2, 15)

Answer 1

Answer:

-5

Step-by-step explanation:

Given these two points, we can just plug them into the slope formula.

$Slope=\frac{y_2-y_1}{x_2-x_1}$

$\frac{15-5}{2-4}\\\\\frac{10}{-2} \\\\-5$

Answer 2

Answer:

-5

Step-by-step explanation:

Rate of Change also slope

Slope = y-y1/x-x1 = tanα = y/x

15-5/2-4 = 10/-2 =-5
