Question

What is the slope from the coordinate points (2,6) (1,9)

Answer 1

-3

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

Answer 2

`m=-3`

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

Explanation:

Step 1: Define

Point (2, 6)

Point (1, 9)

Step 2: Find slope m

1. Substitute:
   `m=(9-6)/(1-2)`
2. Subtract:
   `m=(3)/(-1)`
3. Divide:
   `m=-3`
