To set up the distance formula to find the distance between points E and F, you typically use the formula:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
Where \((x_1, y_1)\) and \((x_2, y_2)\) are the coordinates of points E and F, respectively.
From the provided options, the correct setup for the distance formula will depend on the actual coordinates of points E and F (which we cannot see since there is no image). However, if you provide the coordinates of these points (for example, let’s say E is (2, 5) and F is (6, 1)), it would be set up as follows:
\[ d = \sqrt{(6 - 2)^2 + (1 - 5)^2} \]
This matches with the first response you provided:
\[ d = \sqrt{(6 - 2)^2 + (1 - 5)^2} \]
So the correct way to set up the distance formula based on that format would be:
d = √((6 - 2)² + (1 - 5)²).
If you provide the specific coordinates for points E and F, I can help verify the correct response based on that.
