How many points do you need to draw a line?
• One
• Two
• Three

Finding Slope
•To find slope, use the graph to find the rise and the run from one point to another point (more on this in the next unit)!

Rise
•Rise: how far you go up (positive) or down (negative).
•Run•Run: how far you go right (positive) or left (negative).

Now that we have our line lets find its slope.
Remember we are finding the following ratio: Vertical or Rise
Horizontal Run
