Answer:
Step-by-step explanation:
Rotations are easy when its multiples of 90 degrees; 90,180,270,360. Treat them like they’re a complex number like [x+yi]*i=[-y,xi] so rotating by 90 degrees and 180 is i squared [-1]! So [-3,2] rot90 is [-2,-3].
Reflection about the y=x line is change places. [x.y]=[y,x].
So [-2.-3] reflected about the y=x line is [-2.-3]=[-3.-2],
Compile a list of these transform is best practice technique in this area.

Answer:
A
Step-by-step explanation:
Use formula : Y-y1=m(x-x1)
(x1,y1) = the points given in each situation
6. Y-0=1(x-2)
Y=x-2 or x-y-2=0
7. Y-(-1)= -1/3(x-(-3))
Y+1= -1/3x + 1
3y=-x or x+3y=0
8.Y-4=3(x-5)
Y-4= 3x - 15
Y=3x -11 or 3x-y-11=0
