Describe the effect of dilutions translations rotations and reflections on two-dimensional figures using coordinates

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.

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?

Cd is the perpendicular bisector of both xy and st, and cy=20. find xy.
