Question

Find the slope of the line that goes through (-1,2) and (-1,9)

Answer 1

Answer :

Answer is slope m= undefined

Step-by-step explanation:

Given points are (-1,2) and (-1,9)

$we \: know \: that \: \\ slope = \frac{y2 - y1}{x2 - x1} \\ here \: x1 = - 1 \: \: \: x2 = - 1 \\ y1 = 2 \: \: y2 = 9 \\ on \: substituting \: the \: values \: \\ = \frac{9 - 2}{ - 1 - ( - 1)} \\ = \frac{7}{ - 1 + 1} \\ = \frac{7}{0} \\ = \infty \\ hence \: the \: slope \: is \: undefined$
