$y + 2 = 0$ , $(- 7, 0)$

Step 1

Subtract $2$ from both sides of the equation.

$y = - 2$

Step 2

Use the slope-intercept form to find the slope.

Step 2.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 2.2

Using the slope-intercept form, the slope is $0$ .

$m = 0$

Step 3

The perpendicular line is vertical and the slope is undefined.

$x = - 7$
