Algebra I

• Reading a Cartesian Plane
• Coordinates (x, y)
• Slope Formula:
  `\displaystyle m=(y_2-y_1)/(x_2-x_1)`

Explanation:

Step 1: Define

Find points from graph.

Point (-1, 3)

Point (2, 9)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

1. Substitute in points [Slope Formula]:
   `\displaystyle m=(9-3)/(2+1)`
2. [Slope] Subtract/Add:
   `\displaystyle m=(6)/(3)`
3. [Slope] Divide:
   `\displaystyle m=2`
