The point is and line equation is
.
The above equation compare with slope-intercept form
\y = mx + b, where m is the slope and b is the y-intercept.
\Slope is
If two lines are perpendicular their slopes are .
(Substitute
)
(Simplify)
Apply point-slope form of the line equation is , where
are the coordinates of a point on the line and m is the slope of a line.
(Substitute
)
Apply distributive property: .
(Simplify) \ \
(Add 2 to each side)
(Simplify)
The slope-intercept form of the line equation is .
