What is the slope of the line that passes thought the points (-7,-7)and(-7,1) write your answer in simplest form.

Alexxandr [17]

Answer:

The slope is undefined

Step-by-step explanation:

Find slope by using the slope formula, $m=\frac{y2-y1}{x2-x1}$

Use the given points and insert the x's and y's to solve for slope

(-7, -7) (-7, 1)

$m=\frac{y2-y1}{x2-x1}$

$m=\frac{1-(-7)}{-7-(-7)}$

$m= \frac{8}{0}$

m = undefined

The slope for the given point is undefined because it is impossible to divide a number by 0
