To calculate the distance between the points \( K = (-8, -2) \) and \( G = (-2, 4) \) in the coordinate plane, we use the distance formula:
\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Where:
- \( (x_1, y_1) = (-8, -2) \)
- \( (x_2, y_2) = (-2, 4) \)
Substituting the coordinates into the formula:
1. Calculate \( x_2 - x_1 \):
\[
x_2 - x_1 = -2 - (-8) = -2 + 8 = 6
\]
2. Calculate \( y_2 - y_1 \):
\[
y_2 - y_1 = 4 - (-2) = 4 + 2 = 6
\]
3. Now plug these values into the distance formula:
\[
d = \sqrt{(6)^2 + (6)^2} = \sqrt{36 + 36} = \sqrt{72}
\]
4. Simplifying \( \sqrt{72} \):
\[
\sqrt{72} = \sqrt{36 \times 2} = 6\sqrt{2}
\]
So, the distance \( d \) between the points \( K \) and \( G \) is
\[
\boxed{6\sqrt{2}}
\]
\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Where:
- \( (x_1, y_1) = (-8, -2) \)
- \( (x_2, y_2) = (-2, 4) \)
Substituting the coordinates into the formula:
1. Calculate \( x_2 - x_1 \):
\[
x_2 - x_1 = -2 - (-8) = -2 + 8 = 6
\]
2. Calculate \( y_2 - y_1 \):
\[
y_2 - y_1 = 4 - (-2) = 4 + 2 = 6
\]
3. Now plug these values into the distance formula:
\[
d = \sqrt{(6)^2 + (6)^2} = \sqrt{36 + 36} = \sqrt{72}
\]
4. Simplifying \( \sqrt{72} \):
\[
\sqrt{72} = \sqrt{36 \times 2} = 6\sqrt{2}
\]
So, the distance \( d \) between the points \( K \) and \( G \) is
\[
\boxed{6\sqrt{2}}
\]
