1. 270 counterclockwise: (x,y)-->(y,-x)

So (3,-4)--> a.(-3,-4)

2. R is 4 units below the x axis. When reflected, it is 4 untis above the x axis. So R' would be a. (3, 4)

3. Translating 13 units up is essentially the same as adding 13 to the y point so -4+13=9. So R' would be d. (3,9).

4. A scale factor of 1/5 results in 1/5 of all the points.

L(0,10)-->L'(0,2)

M(-5, -5)-->M'(-1,-1)

J(0,-10)-->J'(0,-2)

K(5,-5)-->K'(1,-1)

So the answer is b.
