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.
\Graph of the slope-intercept form in perpendicular line equation is .
