Question

What is the rate of change?

Answer 1

Gradient = rise/run

= 4/1

So, rate of change is 4

Hope this helps!

Answer 2

Well rate of change is slope. Which is change in y over change in x so find two coordinates so let's say (0,20) and (10,60). The change in y is 40 and the change in x is 10 so the rate of change or slope is 40/10 or Slope= 4

Answer: 4
