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 2, 0 for x, y)

                      (Multiply: )

Apply addition property of equality: If a = b than a + c = b + c.

     (Add to each side)

           (Apply additive identity property: )

                              (Apply additive inverse property: )

Substitute for m and for b in the Slope-intercept form line equation.


The line equation in slope-intercept form is .
