d.) 21

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

hey there : ) your answer would be a.

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
