Question

53:PLEASE HELP Does -x+4y=-5 represent a direct variation yes or no please explain

Answer 1

Answer:

No

Step-by-step explanation:

1. Solve the equation for y.

-x + 4y = -5

      4y = x + 5

        y = (x + 5)/4

2. Check for direct variation

The formula for direct variation is

y = kx,  

where  

k = the constant of variation

An important consequence is that y = 0 when x = 0.

Set x = 0 for your function and calculate y.

y = (x + 5)/4  = (0 + 5)/4 = 5/4 ≠ 0

The function does not represent a direct variation.
