Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18

The coordinates are: (-4, -6) and (12, 2)

The coordinates are: (-4, -6) and (12, 2)

xy = x ÷x y = 1

xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y

That is the commutative property of equality.

It is not possible to answer the question without information about which sides are parallel.

There are no intercepts because the curve, xy = 4 is asymptotic. When x = 0 (where the y intercept would be) y is infinite, and conversely, when y = 0 x is infinite.

Area of a trapezoid = 0.5*(sum of parallel sides)*height
