Question

Question 3solve the problem.a moving firm charges a flat fee of $45 plus $40 per hour. Let y be the cost in dollars of using the moving firm for x hours. Find the slope-intercept form of the equation. ay = 40x + 45 by = 40x - 45 cy = 45x - 40 dy = 45x + 40

Answer 1

slope (m) = rate.    $40 per hour is the rate, so m = 45

y-intercept (b) = one time fee.   $45 is the flat rate which is the one time fee, so b = 45

y = mx + b

y = 40x + 45

Answer: A
