Which relation is a function? A) y2 - x = 8 B) y2 + 3xy = 9y C) y2 + x = 8x - 8 D) 3 y = у

b is the correct answer

you first to choose the points and then move from then as the slope you have

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 .
