This one is the second part I need help with

Answer:
e) this means that it has a slope of 0 and that the y-intercept would be at 70. This means that the daily cost would stay at $70 no matter how far the distance is.
Equation: y = 70
(I'm sorry if this is wrong, but if it's not I hope it helps!)
Step-by-step explanation:
e) a horizontal line passing through the point of intersection (which is (100,70)) means that it has a slope of 0 and that the y-intercept would be at 70. This means that the daily cost would stay at $70 no matter how far the distance is.
Equation: y = 70
(this is how we would write it since there is a slope of 0)
