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:
