The line equation in slope-intercept form is , where m is the slope and b is the y-intercept.
Compare the equation with slope-intercept form and find the slope of the line.
\Slope of the line (m) = .
If two lines are perpendicular, the slope (m1) of one line is opposite
\reciprocal of the second line slope (m2). It can be represented as, .
So, slope of the line perpendicular to given line is
Substitute =
and m =
