18. The total cost y for a ride based on distance driven x (in miles) for XYZ Taxi is given by the equation y=0.5x+4. The total cost for Quick Ride is given in the table. Distance, mi(x) 1 = 2 | 3 | Total cost, $ (y) | 5.50 6.00 | 6.50 Part A Graph the equation representing XYZ Taxi. Graph the data from the table for Quick Ride on the coordinate plane. 0ty 9 Total cost (8) w st 1| 2| 3!l 4|5 /@g]l|" ' 10 Distance (mi} Part B Calculate, compare ana interpret the slopes and the y-intercepts. O For Quick Ride, the slope is 0.5, so they charge $0.50 per mile. O For Quick Ride, the slope is 2, so they charge $2 per mile. O For XYZ Taxi, the slope is 2, so they charge $2 per mile. 0O For XYZ Taxi, the slope is 0.5, so they charge $0.50 per mile. a For Quick Ride, the y-intercept is 4, so they charge $4 per mile. O For XYZ Taxi, the slope is 0.5, so they charge a $0.50 fixed fee. O For Quick Ride, the y-intercept is 5, so they charge a $5 fixed fee. 0O For XYZ Taxi, the y-intercept is 4, so they charge a $4 fixed fee. 19. The total cost in dollars y of a bus pass for x months in City A is given by =23x+50. The total cost in City B is given by y=23x+45. After graphing both equations on your own paper, which city offers a better deal? How do you know? o City B; The only difference between the two equations is that the slope of City Ais greater than City B, so City B would always be less expensive 0 City B; The only difference between the two equations is the y-intercepts, so the lines would be parallel. City B would always cost less. o City A; The only difference between the two equations is that the slope of City Ais greater than City B, so City A would always be less expensive. O City A; The only difference between the two equations is the y-intercepts, so the lines would be parallel. City A would always cost less
