General Formulas and Concepts:

Pre-Alg

• Order of Operations: BPEMDAS

Alg I

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

Step-by-step explanation:

Step 1: Define

Point (2, 6)

Point (1, 9)

Step 2: Find slope m

1. Substitute:                    $m=\frac{9-6}{1-2}$
2. Subtract:                       $m=\frac{3}{-1}$
3. Divide:                           $m=-3$

Answer 2

Answer:

-3

Step-by-step explanation:

The equation for the slope is the change in y/ the change x.

In order to find the change in y we have to subtract the second y (9) by the first y(6) and do the same for x.

That will be (9 - 6)/(1 - 2) = 3/-1 = -3

Slope is -3
