We can use the slope formula for each of these.

\frac{y.2 - y.1}{x.2 - x.1} = m

1. 5 - 1  / 4 - 2

4 / 2

2

The slope is 2, and it is rising because it is positive.


2. -5 - 0 / 3 - (-1)

-5 / 4

The slope is -5/4, and it is falling because it is negative.


3. 1 - 1 / -3 - 2

0 / -5

0

The slope is 0, and it is a horizontal line. The value of y is not changing per value of x.


4. -5 - 2 / -1 - (-1)

-7 / 0

Undefined

The slope is undefined because it fails the vertical line test.
