First you want to get the same denominator on both of the fractions. So you would multiply 1 2/3 or you can change it into a improper fraction which is a fraction greater than 1. So that would be 5/3 times 2/2. Because you want to get the same denominator. That is 10/6. Then you make 3 1/2 a improper fraction which is 7/2 and multiply it by 3/3 to get 21/6. Next you would add them together and get 31/6 but you have to simplify, so you would divide 31 by 6 and get 5 1/6.
Y = 2x - 6 => slope is 2 For perpendicular lines, m2 = -1/m1 Slope of the required line is -1/2 Required equation is (y - 3)/(x - 0) = -1/2 => y - 3 = -1/2 x => y = -1/2 x + 3
