A baseball team plays in a stadium that holds 56,000 spectators.

Question

. With the ticket price at $11, the average attendance has been 25,000. When the price dropped to $9, the average attendance rose to 28,000. Assuming the demand function, , is linear, find , where  is the number of the spectators. Write  in slope-intercept form.

Answer 1

Use two-point form:

(11, 25) and (9, 28) $ in thousands

(y- 25) / (x - 11) = (28 - 25) / (9 - 11)

Can you convert to slope-intercept form and answer?
