The equation is
.
Rewrite equation in slope-intercept form
.
Find the y-intercept, substitute x = 0.
\
y = 4
\So, the coordinate points is (0, 4).
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
(0, 4) and
in the point-slope form
.


Add 4 to each side.
\

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