Question 256075
x=2 is a vertical line going through (2,y)
A perpendicular line would be horizontal going through (2,y) and from the point (-4,1) we know the y value is 1 so the point C intersection of the lines is (2,1)
An equation for that line could  be y=1 (There are an infinite number of such lines)
2-(-4)=6
2+6=8
since x=2 bisects the line AB
point B should be (8,1)
