9.)

The image of point (-6, 2) after a 90° counterclockwise rotation is (-2, -6). This is because a 90° counterclockwise rotation is the same as a 270° clockwise rotation, which is (x, y) → (-y, x).

10.)

The image of point (-9, 3) after reflective it over the line y = x is (3, -9). This is because a reflection over the line y = x is (x, y) → (y, x).

11.)

The blank is "rigid" because rigid transformations preserve length.

There shouldn't be any divison with this problem. If one gallon gets you thirty miles, then 13 gallons would get you 13 x 30 miles. There's no need for fractions. (He'd drive 390 miles on 13 gallons, by the way)
