To find the distance between two points using the Pythagorean Theorem, we can follow these steps:
1. Identify the coordinates of the two points: (-1, 6) and (5, -2).
2. Subtract the x-coordinates and the y-coordinates separately to find the differences between the two points:
Δx = x2 - x1 = 5 - (-1) = 6
Δy = y2 - y1 = -2 - 6 = -8
3. Plug the differences into the Pythagorean Theorem formula, which states that the square of the hypotenuse (distance) is equal to the sum of the squares of the other two sides:
c^2 = Δx^2 + Δy^2
c^2 = 6^2 + (-8)^2
c^2 = 36 + 64
c^2 = 100
4. Take the square root of both sides to find the length of the hypotenuse (distance):
c = √100
c = 10
Therefore, the length between (-1, 6) and (5, -2) is 10 units. The correct answer is 10.
