perpendicular to $y = - 5$ that passes through $(- 1, 4)$

Step 1

Use the slope-intercept form to find the slope.

Step 1.1

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 1.2

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

$m = 0$

Step 2

The perpendicular line is vertical and the slope is undefined.

$x = - 1$
