In slope-intercept form,
the equations are as follows:

These are perpendicular because if you multiply their slopes (-6 and ), you will get

Proof? See the figure above!

x � 6y = 24
6x + y = 6
.
-6y=-x+24
y=(1/6)x-4
.
y=-6x+6
.
they are perpendicular because the slope of one is the negative reciprocal of the other. (1/6 and -6)
