First we need to rewrite 3x-5y=8 in slope-intercept form.

The slope of this line is

The line perpendicular to this line will have a slope that is the negative reciprocal of 3/5, which is

This line passes through (3,7).
The equation is given by:

We substitute the point and slope to get:

We multiply through by 3 to get:

Expand to obtain:
