The product of the slopes of this line and the line perpendicular to it is equal to -1.

Note that the slope if the coefficient of x.

Let

$\alpha$

be the slope of the given line.

Let

$\beta$

be the slope of the line perpendicular to it.

I can therefore say,

$\alpha * \beta = - 1$

$( - 4)/(3) * \beta = - 1$

$\beta = ( - 1)/( ( - 4)/(3) )$

$\beta = ( - 3)/( - 4) = (3)/( 4)$

The slope is 3/4
