Question

What is the slope (2,-9) (-2,3)

Answer 1

-3

Explanation:

-12/4=-3

I got -12 but subtracting two y values, and got 4 by subtracting two x values.

Formula to find slope is= change of y/ change of x=

-12/4= 3

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

Explanation:

Step 1: Define

Point (2, -9)

Point (-2, 3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

1. Substitute [SF]:
   `\displaystyle m=(3+9)/(-2-2)`
2. [Frac] Add/Subtract:
   `\displaystyle m=(12)/(-4)`
3. [Frac] Divide:
   `\displaystyle m=-3`
