A square because when it goes straight down, the shape turns out to be a square. But if you did the cross-section horizontally, it would be a rectangle. I hope that helps answer your question
Since it's parallel, then the slope is the same use the point slope formula and plug in the slope and point y-y1=m(x-x1) y-4=-4(x+2) y-4=-4x-8 y=-4x-4 this is in slope intercept form
