If she raises the price to $1.50 she only sells 400. Assuming a linear relationship between hotdogs sold and the price, come up with the equation of the line that models hotdog sales.etween hotdogs sold and the price, come up with the equation of the line that models hotdog sales.

Explanation / Answer

Points are (1,500),(1,50, 400)

Slope = (400-500)/(1.5-1) = -100/0.5 =-200

Using point slope form which is

s-s1=m(p-p1)

s-500=-200(p-1)

s= -200p +700
