- How do you find x-intercepts and y-intercepts of a graph of an equation?arrow_forwardHow do you find x-intercepts and y-intercept of a graph of an equation?arrow_forwardA car rental company charges a flat fee of $18.30 plus $0.15 per mile. Part 1 of 2 (a) Write an equation that expresses the cost y of renting a car if the car is driven for x mi. The equation is y = 0.15x + 18.30 Part: 1/2 Part 2 of 2 (b) Using the equation from part (a), find the cost of driving the rental car 50, 100, and 200 mi. The cost of driving 50 miles is S The cost of driving 100 miles is S The cost of driving 200 miles is $arrow_forward
