Are the graphs of −5y = 2x + 3 and y=2/4x+4 parallel, perpendicular, or neither?

What we can do is solve both equations for "y", so they end up in slope-intercept form, noticing that the second equation is already in slope-intercept form.

now, keep in mind that parallel lines, have the same slope, and perpendicular ones have a negative reciprocal slope.



notice, the slopes differ, so clearly they're not parallel.

are they perpendicular?  well, the product of the perpendicular ones gives -1, let's check,   

nope, no -1 as product, thus they're not perpendicular either, so they're neither then.

The area would be 280 because if each side is 4 and there are 7 sides all you have to do is 4 times 7 which is 28 then do 28 times 10 since it’s the night and you get 280 as your area
