Hello : let the slope : a and ; b the slope of the line : 5x - 3y = 8 <span>the line that is perpendicular to 5x-3y=8 so : a×b = - 1 but : 5x - 3y = 8... y = (5/3)x - 8/3 when : b = 5/3 </span><span> the slope intercept form of the equation of the line that is perpendicular to 5x-3y=8 is : y = (5/3)x +c </span>
