x=6/5 y=8/5 are the coordinates of the intersection point, but that does not tell you if the lines are perpendular or not.
The slope of the first line is 1/2.
The slope of the second line is -2.
Because the product of the slopes is -1, they are perpendicular.
Is the following pair of lines paralle or perpendicular? Prove the answer.
2y-x=2
y+2x=4
I think that the lines are perpendicular but do not know how to work the problem.
x=6/5 y=8/5 Can some one show me how to work this equation?
