To find the distance between two points in a coordinate plane, we can use the Pythagorean theorem.
The distance between (2, 4) and (5, -2) can be found using the following steps:
Find the difference in the x-coordinates: 5 - 2 = 3
Find the difference in the y-coordinates: -2 - 4 = -6
Use the Pythagorean theorem to find the distance: d = √(3^2 + (-6)^2) = √(9 + 36) = √45
So the distance between (2, 4) and (5, -2) is √45.
