Use two ordered pairs to write a prediction equation. Then using your prediction equation to predict the number of comic books sold when the price is $4.50.

The table is as follows:
Price-$2.00 # sold was 16
-$2.50 13
-$2.75 12
-$3.00 10
-$3.50 7

I used (2.00,16) & (3.00, 10) to get the prediction equation y=-6x + 4 but do not know how to solve for the # of books sold when the price is $4.50.
