Question

What's the slope of (2, 1) (4,5)

Answer 1

`\displaystyle m = 2`

General Formulas and Concepts:

Algebra I

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

Explanation:

Step 1: Define

Identify

Point (2, 1)

Point (4, 5)

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 = (5 - 1)/(4 - 2)`
2. Subtract:
   `\displaystyle m = (4)/(2)`
3. Simplify:
   `\displaystyle m = 2`
