Answer:
Your solution is (1, -4)
Step-by-step explanation:
The equations both equal y, so you can set them equal to each other.
y = -4x
y = -3x - 1
-4x = -3x - 1
add 3x to both sides
-x = -1
divide both sides by -1 for x to be positive
x = 1
plug x back in
y = -4(1)
y = -4
y = -3(1) - 1
y = -3 - 1
y = -4
Your solution is (1, -4)
