Answer:

Infinite solutions.

Step-by-step explanation:

-4x = y + 3......(1)

y = -4x - 3........(2)

Rearranging equation (1)

y = -4x - 3 ------(3)

Adding (2) and (3) we get

0 = 0.

The original equations are identical and their graph will be the same straight line.

Any point on the line is a solution of this system, so there are infinite solution.
