Question

What’s the rate of change this is a review how do you solve this

Answer 1

Rate of change is the same slope

To find the slope, pick any two point from the line and then locate its coordinates

(0, 1) and (1, -1)

x₁ = 0 y₁=1 x₂ = 1 y₂=-1

substitute the values into the formula below;

`\text{slope =}(y_2-y_1)/(x_2-x_1)`

`=(-1-1)/(1-0)`

`=-2`
