O A. y = x + 4
O B. y=-x-4
O C. y = -x+4
O D. y = x-4

y = x +4

Step-by-step explanation:

the slope is 1

the y-intercept is (0,4)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
