Answer 1

To find the distance between two points on a coordinate plane, we can use the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Applying this formula to the points (9,2) and (3,6), we have:

d = √((3 - 9)^2 + (6 - 2)^2)
= √((-6)^2 + 4^2)
= √(36 + 16)
= √52
≈ 7.2 units

Therefore, the distance between these two points is approximately 7.2 units.
