Question

Tell whether the equation 4x + y = 3 represents a direct variation. If so, identify the constant of variation.

Answer 1

y=-4x+3

Explanation:

4x + y=3

4x gets switched to the other side so that it is by its self

which then the equation is going to be y=-4x+3 bc the sin changes

Answer 2

No, this is not direct variation

Explanation:

4x + y = 3

Solve for y

Subtract 4x from each side

4x-4x+y = -4x+3

y = -4x+3

This is not a direct variation because we are adding 3

The form of direct variation is y= kx
