• Reading a coordinate plane
• Coordinates (x, y)
• Slope Formula: $\displaystyle m = \frac{y_2-y_1}{x_2-x_1}$

Step-by-step 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]:                                                              $\displaystyle m = \frac{1--1}{1-0}$
2. [Fraction] Subtract:                                                                                           $\displaystyle m = \frac{2}{1}$
3. [Fraction] Divide:                                                                                               $\displaystyle m = 2$
