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.
