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

Step-by-step explanation:

*Note:

Rate of change is slope.

Step 1: Define

Identify.

Point (-1, -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]:                                                              $\displaystyle m = \frac{-1 + 1}{1 + 1}$
2. [Order of Operations] Simplify:                                                                        $\displaystyle m = \frac{0}{2}$
3. Simplify:                                                                                                             $\displaystyle m = 0$
