Question

Find the distance between the points (-2,3) and (3,-9)

Answer 1

13 units

Explanation:

Put the numbers in the distance formula and do the arithmetic.

d = √((x2 -x1)² +(y2 -y1)²)

= √((3 -(-2))² +(-9-3)²) = √(5² +(-12)²) = √(25 +144)

d = √169 = 13

The distance between the points is 13 units.
