Video of the Day "Slope of Line"

Today I have two videos posted on slope. These are very basic videos on slope,but you have to learn to walk before you can run.

Video 1
When a line has a negative slope the line slopes downward when you move from left to right. Notice that as y decreases, x increases. When a line has a negative slope the two variables move in opposite directions. Video explains and demonstrates a negative and positive slope of a line.

Video 2
What is an undefined slope and what does it look like on a graph. The video goes what a line looks like that has an undefined slope and why.
