Answer:
The answer to your question is: x = -1
Step-by-step explanation:
Data
slope of l = x
slope of m = x +2
they are ⊥
Process
If they are ⊥, then, x + 2 = - 1/x
x(x + 2) = -1
x² + 2x = -1
x² + 2x + 1 = 0
(x + 1)² = 0
x + 1 = 0
x = -1
Answer:
A = (-2 , -1) A’ = (-5 , -1)
B = (2 , -1) B’ = (-1 , -1)
C = (2, 2) C’ = (-1 , 2)
Step-by-step explanation:
Move each coordinate to the left 3 times! You will result in the prime coordinates of the letters!
