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.

  2. The relationship between price and number sold is not quite linear. If you choose prices of = = 2.50 and 3.50 to get a prediction equation, the straight-line fit would be
    y = 28 - 6x
    Then if x = 4.50, the number sold is
    y = 28 - 27 = 1
