Graphing and Writing Linear Equations
- Chris Hood
Refresher on finding slope using 2 points. It is only 3 minutes long.
1. Answer the following. Show how.
What is the slope of the line that contains the points ( -3, -5) and ( -7, 8 ) ? Show your work.
2. Answer the following. Explain.
What is the slope of the line that contains the points ( -9, 12) and (-9, 15)?
3. Answer the following
Based on the answer to the previous question, what about the ordered pairs reveals this unique value for slope? What would the line look like?
4. Answer the following.
If the y-coordinates are the same for two ordered pairs, what is the value of the slope and what would the line look like?
