The equation is
.
Find the x-intercept, substitute y = 0.
\
Add
to each side.


Multiply each side by 2.
\

So, the coordinate points is (
8, 0).
If two lines are perpendicular, the slope (
) of one line is opposite reciprocal of the second line slope (
). It can be represented as,
.
So, slope of the line perpendicular to given line is
.
Substitute
and
in the point-slope form
.


\ \
The slope-intercept form in perpendicular line equation is
.
Graph each line on a coordinate planes.
\
Graph of the slope-intercept form in perpendicular line equation is
