Question

Find the slope between (2, -1) and (2,5) by graphing or solving..

Answer 1

Explanation:

I think the easiest way would be to plot the points onto a graph. See the attached graph.

If you want to solve it, you can use the slope formula:

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

Where m = slope

From the two points we are given:

(2, -1) -----> x1 = 2 , y1 = -1

(2,5) -----> x2 = 2 , y2 = 5

Plug these values into the slope formula and you get:

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

m =
`(5 - (-1))/(2 - 2)` =
`(5 + 1)/(0) = (6)/(0)` = ∞

This means that the slope m = ∞. In other words, there is no slope or gradient because the line is vertical.
