Find an equation of the line (in slopeintercept form) that passes through the point (7,5) and is perpendicular to the line 7x + 10y  17 = 0
y=?

First put the perpendicular line equation into y=mx+b form. Your first step should be to subtract the 10y from both sides.
Then using the y = mx + b equation, you know the slope of the parallel line. Your line is perpendicular to the m value in the new equation. To find the slope use: 1/m. That number will be your m value in your equation.
Finally plug your numbers into the basic starter equation:
y(yval)=m(x(xval))
your yval and xval numbers are from the point the line passes through
