ANSWER
EXPLANATION
We determine the slope of each line using the slope formula;
The slope of BC is
The slope of AB is
The two lines are perpendicular so the product of their slopes is -1.
This implies that,
.

Answer:
It has one solution (1,0)
Step-by-step explanation:
y = -2x + 2
y = 4x -4
Substitute the y's
4x - 4 = -2x + 2
Let's move the variables to one side
4x - 4 = -2x + 2
+2x +2x
6x - 4 = 2
Lets move the constant to the other side
6x - 4 = 2
+4 +4
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
Let go back to y = -2x + 2
Substitute the x with 1
y = -2(1) + 2
y = -2 + 2
y = 0
