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

Step-by-step 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]:                                                            $\displaystyle m=\frac{9-3}{2+1}$
2. [Slope] Subtract/Add:                                                                                     $\displaystyle m=\frac{6}{3}$
3. [Slope] Divide:                                                                                                  $\displaystyle m=2$
