$-5/13$

The slope of any line perpendicular to a line of slope $m$ is $-1/m$

In our example, the equation is in slope intercept form, so the slope is easily read as the coefficient of $x$ , namely $13/5$ .

Hence the slope of any line perpendicular to this line is:

$-1/(13/5) = -5/13$

What is the slope of the line perpendicular to y=13/5x-3 y=13/5x-3 ?
