Question

Which equation represents a line which is perpendicular to the line y = 4/3x -7

Answer 1

Answer:

A)3x + 4y = 8

Step-by-step explanation:

Given expression;

          y = $\frac{4}{3} x$   - 7

A line perpendicular to this will have negative inverse slope;

  the slope of the given line = $\frac{4}{3}$

  perpendicular line  = $-\frac{3}{4}$  

 Now;

      the equation of the line is;

 

           y =  $-\frac{3}{4}$ x  - 7

  multiply through by 4

          4y  = -3x - 28

          4y + 3x  = -28
