    Do you know the formula for the average rate of change?

    \[M = \frac{ {y2}-y1 }{ x2-x1 }\]

    So they're asking for the average rate of change from x = -2 to x = 0. So we have two ordered pairs. (-2, y1) and (0, y2). On the graph it shows that the y's are both -1. So yes you plug in the ordered pairs into the formula. \[M = \frac{ -1 - (-1) }{ 0 - (-2) }\]

    You shouldn't get an ordered pair when you solve it. Also, when you put -1 - (-1) 0-2. You forgot that the 2 is also negative so it'd actually be 0 - (-2). The subtraction signs become addition/positive of course. So your equation becomes \[M = \frac{ -1+1 }{ 0 + 2 }\]
