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

Step-by-step explanation:

Step 1: Define

Point (80, 20)

Point (120, 30)

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]:                                                             $\displaystyle m=\frac{30-20}{120-80}$
2. [Slope] Subtract:                                                                                              $\displaystyle m=\frac{10}{40}$
3. [Slope] Simplify:                                                                                               $\displaystyle m=\frac{1}{4}$
