Question

Slope of the line through each ordered pair of points
(18,-5)(18,20)

Answer 1

Answer:

Undefined

Step-by-step explanation:

Slope can be found using:

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Let's call (18, -5) our first pair, and (18,20) our second

So, x1 is 18, x2 is 18, y1 is -5, and y2 is 20, and we can substitute them in $m=\frac{20- -5}{18-18}$

$m=\frac{25}{0}$

Since any number divided by 25 is undefined, the slope is undefined
