The ordered pair below is a solution to which equation? (40, 5)

A. y = 8x

B. y = 5x

C. y = 1/8x

D. y = 1/5x

C. y = 1/8x

because 5 = (1/8) (40)

5=5

All we have to do here is to express numbers 40 and 5 in each of equations. Note that first number in brackets is always x coordinate and second number is y coordinate

First equation:

5 = 40*8 false

Second

5 = 5*40 false again

Third:

5 = 40/8 = 5 True

checking for just in case last one:

5 = 40/5 = 8 False

Correct one is C)
