Algebra I

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

Explanation:

Step 1: Define

Point (5, 9)

Point (-3, 9)

Step 2: Identify

x₁ = 5, y = 9

x₂ = -3. y = 9

Step 3: 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=(9-9)/(-3-5)`
2. [Slope] [Fraction] Subtract:
   `\displaystyle m=(0)/(-8)`
3. [Slope] [Fraction] Divide:
   `\displaystyle m=0`
