Question

Given the points below, find XY. Round to the nearest hundredth.
X(-8,4) and Y (4, -6)

Answer 1

15.62

Explanation:

The length XY is found from the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((4 -(-8))² +(-6 -4)²) = √(12² +(-10)²) = √244

d ≈ 15.62 . . . units

The length of XY is approximately 15.62 units.
