Need help guys! The problem starts off with 5x+3y=4, and we figured that out to be y=-5/3x+4/3

Then he says to figure the line's slope which I figured to be -5/3, then he goes on to say find an equation for the parallel line through (3,2) which I figured out to be y=-5/3x+7, then he goes on to say to find an equation for the perpendicular line through (3,2). Can't figure that last part out, please help! you guys rock!
