Cd is perpendicular to ab and passes through point c (5,12).

if the coordinates of a and b are (-10, -3) and (7, 14), respectively, the x- intercept of cd is:

(12, 0)
(15, 0)
(17, 0)
or (19,0).

the point:

(-5, 24)
(-2, 19)
(7, -10)
or (8, 11)

lies on cd.

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
