    The demand function gives quantity demanded (tickets sold) as a function of price (x). You are told: when x= 8 dollars, attendence is 20000--> so (8, 20000) is a point on the line When x= 7 dollars, attendence is 25000--> so (7, 25000) is a point on the line So you have 2 points on the line. Find the slope, then use one point and the slope to write the equation.

    Hmmmmmm...... no, that doesn't look right. How did you get that? The slope is correct, but not your y-intercept.
