  • Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step-by-step explanation:

Step 1: Define

Point (-9, 3)

Point (7, -1)

Step 2: Find slope m

  1. Substitute:                    [tex]m=\frac{-1-3}{7+9}[/tex]
  2. Subtract:                       [tex]m=\frac{-4}{16}[/tex]
  3. Divide:                          [tex]m=\frac{-1}{4}[/tex]

Answer:

slope=-1/4

Step-by-step 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
