In order to find the x- intercept, we need to find the function. Using the point slope formula:
y = 2x/5
The x intercept is when y = 0, so the x intercept is (0,0). (also the y intercept)
h is a function, so in order to find h(x), plug 45 into the equation :
h(45) = (1/9) * (90 - 45)
h(45) = 45/9 = 5
So the answer is B
H is a function, so in order to find h(-67), we just need to plug in -67 into h(x):
h(-67) = -49*-67 -125 = 3158
