The graphs represents y=-1/4x-3 which coordinate is not a solution for the equation. (-2,-4) or (0,-3)

1 answer

To determine which coordinate is not a solution for the equation y = -1/4x - 3, we substitute the x and y values of each coordinate into the equation and see if it is satisfied.

For (-2, -4):

y = -1/4x - 3

-4 = -1/4(-2) - 3

-4 = 1/2 - 3

-4 = -2.5

The equation is not satisfied when we substitute the x and y values of (-2, -4) into the equation, so (-2,-4) is not a solution for the equation.

For (0, -3):

y = -1/4x - 3

-3 = -1/4(0) - 3

-3 = 0 - 3

-3 = -3

The equation is satisfied when we substitute the x and y values of (0, -3) into the equation, so (0,-3) is a solution for the equation.

Therefore, the coordinate that is not a solution for the equation is (-2,-4).
