The slope of the graph is the difference of y- values over the difference in x-values.

$Slope=(\Delta y)/(\Delta x)$

The diffrence in y- values is

$\Delta y=450-50=400$

and the difference in x-values is

Hence, the rate of change (or the slope ) of the graph is

$\text{slope = }(400)/(8)$
$\text{slope}=(\$50)/(yr)$

which is our answer!
