Question 18

kobusy [5.1K]

Answer:

Undefined

Step-by-step explanation:

$y=-7$ has a slope of $0$ , since it is a horizontal line. The only types of lines that are perpendicular to horizontal lines are vertical lines, which are usually in the form $x=a$ (where $a$ is any real number). Vertical lines have an undefined slope, so the answer is undefined. Hope this helps!
