Question

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

Answer 1

Answer:

$m=-7$

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS

Algebra I

• Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from chart.

Point (39, 36)

Point (40, 29)

Step 2: Find slope m

1. Substitute:                    $m=\frac{29-36}{40-39}$
2. Subtract:                       $m=\frac{-7}{1}$
3. Divide:                          $m=-7$

Answer 2

(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
