Aline segment can be drawn between any two points

Only one line segment can be drawn between two points. Any other line segments would be overlapping and the same segment.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
