A' (2,5)
B' (3,6)
When reflecting over only y axis, flip the negative/positive sign for the x value
When reflecting over only x axis, flip the negative/poditive sign for the y value
We can use point slope form to solve for this.
y - 1 = -2(x - 2)
Simplify.
y - 1 = -2x + 4
Add 1 to both sides.
y = -2x + 5
Now, we can input -3 for x and solve for y, or r in this case.
y = -2(-3) + 5
y = 6 + 5
y = 11
r = 11
KL will be 2x +19
11 + 2x+19 = x+21
x= -9
KL = 1
