what is the distance between (2, -1) and (2, 3)
The distance between two points in a coordinate plane can be found using the distance formula. The formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the coordinates are (2, -1) and (2, 3).
Using the formula, we get:
d = sqrt((2 - 2)^2 + (3 - (-1))^2)
= sqrt(0^2 + 4^2)
= sqrt(0 + 16)
= sqrt(16)
= 4
Therefore, the distance between (2, -1) and (2, 3) is 4 units.
