Question

please help 30 points !! in a proportional relationship when Y=2 when X=8 Which of the following equations would describe this relationship?

Answer 1

(1)

Explanation:

We will try:

(1) y =
`(1)/(4)`x => 2 = 2 (seems legit)

(2) y = 4x => 2 = 32 (nope)

(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)

(4) y =
`(1)/(2)`x - 2 => 2 = 2 (like the above)
