For the straight line defined by the points (2, 57) and (4, 91) , determine the slope and y-intercept. do not round the answers.

Aline of best fit is drawn for the set of points shown on the graph. which point is an approximate extrapolation for x = 30 from the line of best fit?

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.

What is the difference between the equations of a vertical and a horizontal line?
