Hello : let the slope : a and ; b the slope of the line : 6x - 3y = 2 <span>the line that is perpendicular to 6x-3y=2 so : a×b = - 1 but : 6x - 3y = 2... y = 2x-2/3 when : b = 2 </span><span> in point - form form of the equation of the line that is perpendicular to 6x-3y=2 is : y = (-1/2)x +c </span>contains (5,1) : 1 = (-1/2)(5) +c c = 7/2 an equation is : y= (-1/2)x +7/2
basicallyi you want to find a common denominator before you add them up. the common denominator in this case would be 20, since it's the first common multiple all of them share
