I KEEP GETTING ANSWER WRONG AND I DON'T UNDERSTAND WHY! Write an equation of the line passing through point P that is perpendicular to the given line.
P(−1,−2), y=−4x+13
I KEEP GETTING EITHER 1x+1 or 1x+3

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
