Question

What is the slope of the line that contains these points?

Answer 1

(Y2-y1)/(x2-x1) slope formula
Pick any two points: (39,36), (40,29)
(29-36)/(40-39) = -7/1 = -7
The slope is -7

Answer 2

`m=-7`

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS

Algebra I

• Slope Formula:
  `m=(y_2-y_1)/(x_2-x_1)`

Explanation:

Step 1: Define

Find points from chart.

Point (39, 36)

Point (40, 29)

Step 2: Find slope m

1. Substitute:
   `m=(29-36)/(40-39)`
2. Subtract:
   `m=(-7)/(1)`
3. Divide:
   `m=-7`
