Can someone me with my math? (the page)

Question 1 part B (You've got A) Ben's rate of change (Slope) Is 0.15 Shown as the variable m in the equation y=0.15x+49

Question 2 part A Angela's initial value is 60 (Y-intercept) shown on the graph at the point (0,60)

Question 2 part B Ben's initial value is 49 (Y-intercept) shown as the variable b in the equation y=0.15x+49

Question 3 part A Angela's price for talking 200 minutes would be 80$ as shown on the graph as the point (200, 80) (the answer is the y value)

Question 3 part B Ben's price if he talked for 200 minutes would be 79 if you substituted 200 for the x value, multiplied it by 0.15 then added 49, you'd get 30+49 to give you 79$ as your final cost.
