We will be using the above formula. The answer will be a bit rough.

Okay. So our two points are (-10, 6) and (-15, 7). The number first in the brackets is always the 'x' variable while the second number in the bracket is always the 'y' variable. I will be using ² instead of the bottom 2 (As shown in the formula).

x = -10 x² = -15

y = 6 y² = 7

7 - 6

m = ———

- 15 - (-10) = -15 + 10

1

m = ——— OR - 0.2

- 5

  • Coordinates (x, y)
  • Slope Formula:
    \displaystyle m=(y_2-y_1)/(x_2-x_1)

Explanation:

Step 1: Define

Point (-10, 6) → x₁ = -10, y₁ = 6

Point (-15, 7) → x₁ = -15, y₁ = 7

Step 2: Find slope m

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

  1. Substitute in points [Slope Formula]:
    \displaystyle m=(7-6)/(-15+10)
  2. [Fraction] Subtract/Add:
    \displaystyle m=(1)/(-5)
  3. [Fraction] Convert:
    \displaystyle m=-0.2
