Answer:

y = -1/3 x + 32/3

Explanation:

Find an equation of line L

Given the equation bog L1 as y ,= 3x-4

The slope of the line L1 is 3

Since both lines are perpendicular, the product of their slope is -1, hence ;

LL1 =-1

3L = -1

L = -1/3

Slope of the required line is -1/3

Get the equation in point lope form

y-y0 = m(x-x0)

y-9 = -1/3(x-5)

3(y-9) = -(x-5)

3y-27 = -x+5

3y = -x+5+27

3y = -x+32

y = -1/3 x + 32/3

This gives the required equation
