You can
put this solution on YOUR website!2x-7y=5 and 2y-7x=7
:
Put both equation into the slope/intercept form
-7y = 5 - 2x
7y = 2x - 5; multiplied equation by -1
y =
x -
and
2y = 7x + 7
y =
x +
:
not parallel, they have different slopes
:
slope relationship for perpendicular lines: m1 * m2 = -1
*
= +1, so not perpendicular either
