Question

Find the distance between A and B.

Answer 1

A

Explanation:

A: (-2,1)

B: (3,0)

AB = sqrt[(1-0)² + (3--2)²]

AB = sqrt[1 + 25]

AB = sqrt(26)

Answer 2

sqrt(26)

Explanation:

Point A = (-2,1) and B = (3,0)

The distance is found by

d = sqrt( (x2-x1)^2 + (y2-y1) ^2)

= sqrt( ( 3 --2) ^2 + (0-1)^2)

= sqrt( ( 3 +2) ^2 + (0-1)^2)

= sqrt( 5^2 + (-1)^2)

= sqrt( 25+1)

= sqrt(26)
