Question

Find the slope between (-9,3) and (7,-1).​

Answer 1

slope=-1/4

Explanation:

slope formula- (y2-y1)/(x2-x1)

plug in the coordinates

-1-3/7--9

two negatives equal a positive so.......

-1-3/7+9

-1-3=-4

7+9=16

-4/16

simplify

-1/4

Answer 2

`m=(-1)/(4)`

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

Explanation:

Step 1: Define

Point (-9, 3)

Point (7, -1)

Step 2: Find slope m

1. Substitute:
   `m=(-1-3)/(7+9)`
2. Subtract:
   `m=(-4)/(16)`
3. Divide:
   `m=(-1)/(4)`
