Parallel, perpendicular, or neither? 5x+3y=7 3x+5y=4
emmainna [20.7K]
Neither. They can’t be parallel because both lines have different slopes. They aren’t perpendicular either because their slopes don’t multiply to equal -1.

Which graph correctly represents the equation y=−4x−3?
pentagon [3]

Idk if u got the answer or not, but It's the last graph. Just by looking at it you can point two things out.

1. The y intercept is -3 (so the graph needs to have the point (0,-3) that takes out two options.)

2. The slope is negative. (Which means the graph is going to decrease. So that takes out the other two options that have it increased.)
