By definition, the average rate of change of a function f from x = a to x = b is: $\frac{f(b) - f(a)}{b - a}$ This is just the slope of the line between the points (a,f(a)) and (b,f(b)). Now, you try it...

SOOOO confused.

Average rate of change is just the slope of a line between two points. Look at your graph: look at the point when x = 1. Look at the point when x = 2. Can you figure out the slope of the line between those two points?

(Remember that slope is rise/run.)

m=1???? idk lol

My teacher was like screaming at me over the phone yesterday over this lol. I had an awful geometry teacher, so any time I'm given graphs I freeze up.
