Slope intercept form is,

A line perpendicular to that line would have a slope of,

since perpendicular lines have slopes that are negative reciprocals.
Then to get three lines that are perpendicular choose 3 different y-intercepts.

where
Example: Given , three perpendicular lines would be,

If the general form of one equation
looks like:
,
then, for the other line to be perpendicular
to this one, the equation must look like:

--------------------------------------
and are y-intercepts

For example:
For the 1st line:

-----------------
For the 2nd line:

----------------------
Here's the lines:
