Question

Which equivalent represents proportional to the constant proportional equals -2 select all the apply

Answer 1

=> y = 2x

=> y = -2x

=> 2y = -4x

=> y + 2 = 2x + 2

Step-by-step explanation

We want to find the equation(s) that represents a proportional relationship.

A proportional relationship is one that can be written in the form:

y = kx

where k = constant of proportionality

Therefore, the correct options are:

=> y = 2x

=> y = -2x

=> 2y = -4x:

This is because it can be simplified by dividing through by 2 to get:

y = -2x

=> y + 2 = 2x + 2:

This is because it can be simplified by subtracting two from both sides to get:

y = 2x
