Question

What is the slope of the line that passes through the points left bracket, minus, 5, comma, minus, 9, right bracket(−5,−9) and left bracket, minus, 5, comma, minus, 13, right bracket(−5,−13)? Write your answer in simplest form.

Answer 1

undefined

Explanation:

To find the slope of a line given two points on the line, we can use the slope formula:

m = ( y2-y1)/ (x2-x1)

We are given: ( -5,-9) and ( -5, -13)

m = ( -13 - -9)/ ( -5 - -5)

= ( -13+9) / ( -5+6)

= -4/0

We cannot divide by zero so the slope is undefined.
