Answer:
PICK the bottom LEFT graph.
Explanation:
So it's a < sign, there's no equal sign, so it's going to be a dashed line. That means it's either bottom left or bottom right.
Bottom left is correct - - - we want the y to be less than 1-3x.
Pick a point that is shaded on that graph and check your answer.
(0,0)
Substitute this point in the equation and see if it makes sense.
y < 1-3x
0 < 1-3(0)
0 < -2 THIS IS TRUE, and this is exactly what we want shaded in!
