Question

Find the slope: (12, 10), (12, 5)

Answer 1

Indefinite

Explanation:

Slope formula:

`m=(y_(2)-y_(1) )/(x_(2)-x_(1)) \\m=(5-10)/(12-12) \\m=(-5)/(0)\\`

When you have a 0 as denominator, the slope is indefinite; the line on the graph is vertical

Answer 2

sorry about that v but to make it shorter the answer is undefined

Explanation:

To calculate the slope (m) use the

The 2 points here are (12 ,10) and (12 ,5)

Division by 0 is undefined , hence slope is undefined.

This is, in fact, a line parallel to the y-axis and passing through all points in the plane with an x-coordinate equal to 12.

For this reason it's equation is x = 12

A 'quick' way to note when this situation occurs is to observe that the x-coordinates of the 2 given points are equal.
