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

Explanation:

Step 1: Define

Identify points from graph

Point (0, -1)

Point (1, 1)

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 = (1--1)/(1-0)`
2. [Fraction] Subtract:
   `\displaystyle m = (2)/(1)`
3. [Fraction] Divide:
   `\displaystyle m = 2`
