let's recall that perpendicular lines have negative reciprocal slopes, so say for a line with a slope of a/b

a perpendicular one will be -b/a.
what does that mean? well, that the lines are perpendicular of course, they meet at a 90° angle, and two straight lines meeting at 90° can only meet once.
since a solution to a system of equations is where the graph meet, and these two meet perpendicularly once, then that means only one solution.

You have to change the fractions into improper fractions and then change the denominators so they are equal
Question #1:
Just divide the side lengths to find the scale factor.
8 / 2 = 4.
Therefore the scale factor from MNO to M'N'O' is 4.
Question #2:
Rotation rule for 180 degree clockwise turn: (-x, -y)
Therefore your new points will be:
(5, 2), (5, 4), and (4, 4)
