Answer:

3y + 4x = 39

Step-by-step explanation:

The formula for calculating the equation of a line in point-slope form is expressed as:


y-y_0=m(x-x_0)

where;

m is the slope

(x0, y0) is the point on the line

Get the slope of the required line

Given the equation of the line 3x - 4y = 8

Rewrite in standard form

-4y = -3x + 8

y = -3x/-4 + -8/4

y = 3/4 x - 2

The slope of the given line is 3/4

If the equation of the required line is perpendicular to the given line, hence the slope of the required will be:


\begin{gathered} M=(-1)/(((3)/(4))) \\ M=(-4)/(3) \end{gathered}

Get the equation of the required line:


\begin{gathered} y-5=-(4)/(3)(x-6) \\ 3(y-5)=-4(x-6) \\ 3y-15=-4x+24 \\ 3y+4x=24+15 \\ 3y+4x=39 \end{gathered}

Hence the required equation of the line is 3y + 4x = 39
