Steps were not shown. Do you know why, and how to see through the concepts quickly? If you want the equation result to be in slope-intercept form, you simply need to do a couple simple algebra steps.

This is a linear ( straight line ) equation which
is in the slope-intercept form. In general, the
slope-intercept form looks like:
where = slope of the line
--------------------------------
In this case,
The slope of ANY line perpendicular to
this line will have a slope of:
-----------------------
So far, you know the perpendicular line looks like:
The perpendicular line goes through ( 7,-4 )
Use the point-slope formula to find
----------------------------------------
-----------------------------
check answer:
does it go through ( 7,-4 ) ?
OK
Here is the plot of both lines:
