Find the equation of a line that passes through the point (4,2) that is perpendicular to the line y=4/3 x

Simplify \frac{4}{3}x​3​​4​​ x to \frac{4x}{3}​3​​4x​​ y=\frac{4x}{3}y=​3​​4x​​ 2 multiply both sides by 33y\times 3=4xy×3=4x3 regroup terms3y=4x3y=4x4 divide both sides by 44\frac{3y}{4}=x​4​​3y​​ =x5 switch sidesx=\frac{3y}{4}x=​4​​3y​​

than do 23.50 times 18 and then divide your answer by 100 than you will get x.
