Question

Find the slope of the line that goes through the points (-11, -19) & (-11, -10)

Answer 1

The slope is undefined

Explanation:

The slope of a line given two points can be found by using the formula

`m = ( y_2 - y _ 1)/(x_ 2 - x_ 1) \\`

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are (-11, -19) & (-11, -10)

The slope is

`m = ( - 10 - - 19)/( - 11 - - 11) = ( - 10 + 19)/( - 11 + 11) = - (9)/(0) \\`

Any number divided by zero is undefined so the slope of the line here is undefined.

Hope this helps you
