To find the length between the points (2, 5) and (7, 3) using the Pythagorean Theorem, we first determine the differences in the x-coordinates and the y-coordinates.

  1. Calculate the difference in x-coordinates: \[ \Delta x = 7 - 2 = 5 \]

  2. Calculate the difference in y-coordinates: \[ \Delta y = 3 - 5 = -2 \]

  3. Use the Pythagorean Theorem, which states that the distance \( d \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by: \[ d = \sqrt{(\Delta x)^2 + (\Delta y)^2} \]

    Substituting the values we computed: \[ d = \sqrt{(5)^2 + (-2)^2} = \sqrt{25 + 4} = \sqrt{29} \]

  4. Calculate \(\sqrt{29}\): \[ d \approx 5.385 \]

Rounding to the nearest hundredth gives: \[ d \approx 5.39 \]

Therefore, the length between the points (2, 5) and (7, 3) is 5.39.
