Answer:
A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.
Step-by-step explanation:
132=3x+x
132=4x
x=33
The length of the shorter piece is 33 inches
(-1,-4) this is saying that when x=-1, y=-4. Plugging it into the line equation y=4x gives

Which is correct.
