This table shows a linear function.

Which equation represents the function?

the answers available are

A. f(x)= -1/2x + 4

B. F(x) = 4x-2

C. f(x)= -2x + 4

D. f(x)= 2x + 1/2

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.
