Hey i’ll give brainliest please help

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

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.

What’s 8y+48 and factor each expression completely
