Answer:

D. y = 4x

Step-by-step explanation:

y = 4x

Plug in The point (-1,-4) into the equation

when x = -1, y = 4(-1) = -4

So (-1,-4) is the solution of y = 4x

Answer:

D

Step-by-step explanation:

To determine which line the point lies on , substitute the x-coordinate into the equation and if the value of y corresponds to the y-coordinate then the point lies on the line

A

y = x - 4 = - 1 - 4 = - 5 ⇒ point does not lie on the line

B

y = - 4x = - 4 × - 1 = 4 ⇒ point does not lie on the line

C

y = x + 4 = - 1 + 4 = 3 ⇒ point does not lie on the line

D

y = 4x = 4 × - 1 = - 4 ⇒ point lies on the line
