Write an equation in slope-intercept form for the line that has a slope of -4 and passes through (1, 2). a. y = -2x + 4 b. y = -4x + 2 c. y = -4x + 6 d. y = -4x + 9

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.
