$$slope = \dfrac{rise}{run} = \dfrac{\text{change in y}}{\text{change in x}} =\dfrac{y_2 - y_1}{x_2-x_1}$$

2. ineedyouubiebs Group Title

I got 0 is that correct?

3. gypsy1274 Group Title

Yes, it is.

4. ineedyouubiebs Group Title

And how do i know if its a line or a line segment?

5. gypsy1274 Group Title

A line continues on forever in either direction. A line segment has endpoints.

6. ineedyouubiebs Group Title

so it'll be a line segment bc it has an endpoint

7. gypsy1274 Group Title

It seems that way. Usually in a word problem, you will be told if it is a line or a line segment. If there is a picture accompanying this question, a line will have arrows on either end.

8. ineedyouubiebs Group Title

no theres no picture

9. gypsy1274 Group Title

Is what you typed the exact wording of the question?

10. ineedyouubiebs Group Title

yes it is

I'll type it again: What is the slope of CD if C(5,-4) and D(5,2)? Is this a line or a line segment?

I would have to guess that it is a line segment. Maybe I am over-thinking this, but it just doesn't seem clear to me.
