Step 1: Use the distance formula
The distance between two points \( (x_1, y_1) \) and \( (x_2, y_2) \) is given by:
\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Step 2: Substitute values
Given points: \( (7, -4) \) and \( (-5, 1) \):
\[
d = \sqrt{(-5 - 7)^2 + (1 - (-4))^2}
\]
\[
= \sqrt{(-12)^2 + (5)^2}
\]
\[
= \sqrt{144 + 25}
\]
\[
= \sqrt{169}
\]
\[
= 13
\]
Thus, the correct answer is \( 13 \).
