I need help with the first four
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.
