Question

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

Answer 1

C. y =1/8x
because 5=(1/8)(40)
5=5

Answer 2

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)
