Well, the easiest way to go about this is to take out the number of games played (temporarily, we'll need that number later.)
We'll make y the points per game and x the number of games.
Now the way to find this out is to divide the number of points by the number of games so:
y = 64/x
now we know x is 8 so we need to solve for y
y = 64/8
y = 8
Teri scored 8 points per game.
