To find the length between the two points \((-2, -1)\) and \((2, 4)\) using the Pythagorean Theorem, we first need to determine the horizontal and vertical distances between the two points.
-
Calculate the change in x: \[ \Delta x = x_2 - x_1 = 2 - (-2) = 2 + 2 = 4 \]
-
Calculate the change in y: \[ \Delta y = y_2 - y_1 = 4 - (-1) = 4 + 1 = 5 \]
-
Use the Pythagorean Theorem: The length \(d\) between the two points can be found using the theorem: \[ d = \sqrt{(\Delta x)^2 + (\Delta y)^2} \] Substituting the values we calculated: \[ d = \sqrt{(4)^2 + (5)^2} = \sqrt{16 + 25} = \sqrt{41} \]
-
Calculate \(\sqrt{41}\): \[ \sqrt{41} \approx 6.403124237 \] Rounding this to the nearest hundredth gives \(6.40\).
Thus, the length between the two points is approximately 6.40.
