Answer 1

To find the length between the points \((-1, 6)\) and \( (5, -2)\), we use the distance formula, which is derived from the Pythagorean Theorem. The distance \(d\) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by:

\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]

Substituting the coordinates \((-1, 6)\) as \((x_1, y_1)\) and \((5, -2)\) as \((x_2, y_2)\):

- \(x_1 = -1\)
- \(y_1 = 6\)
- \(x_2 = 5\)
- \(y_2 = -2\)

Now we calculate the differences:

\[
x_2 - x_1 = 5 - (-1) = 6
\]
\[
y_2 - y_1 = -2 - 6 = -8
\]

Next, we can substitute these values into the distance formula:

\[
d = \sqrt{(6)^2 + (-8)^2}
\]

Calculating the squares:

\[
d = \sqrt{36 + 64}
\]
\[
d = \sqrt{100}
\]
\[
d = 10
\]

Therefore, the distance between the points \((-1, 6)\) and \( (5, -2)\) is \(10\).

The correct response is:

**10**
