Which equation(s)
represents a proportional
relationship?
a) y = 7x2
b) y = 2 + 3x
c) y = 12x
d) y = 5 - x

C) y = 12 x Represents the proportional  relationship.

Step-by-step explanation:

Two quantities P and Q are said to be proportional if and only if:

Here: K = Proportionality Constant

Now, here the given expression are:

So, y is NOT PROPORTIONAL to x.

So, y is NOT PROPORTIONAL to x.

So, y is  PROPORTIONAL to x.

So, y is NOT PROPORTIONAL to x.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
