First find the slope of the line
.
The line in slope-intercept form y = mx + b, where m is slope and b is y-intercept.
\Compare the equation with slope-intercept form and find the slope of the line.
\ = 
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,
.
Slope of the line perpendicular to given line is 
So, slope of the new line =
.
The line equation in slope-intercept form is
, where m is the slope and b is the y-intercept.
First find the y-intercept value.
\
(Substitute
for m)
(Substitute
5, 7 for x, y)
(Multiply:
)
Apply subtraction property of equality: If a = b than a
c = b
c.
(Subtract 10 from each side)
(Apply additive inverse property:
)
(Subtract:
)
Substitute
for m and
for b in the Slope-intercept form line equation.

The line equation in slope-intercept form is
.
