Algebra I

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

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=(30-20)/(120-80)`
2. [Slope] Subtract:
   `\displaystyle m=(10)/(40)`
3. [Slope] Simplify:
   `\displaystyle m=(1)/(4)`
