Question

find the distance between the point (3, 1) (0, -2)​

Answer 1

Let A(3, 1) = x1, y1

and B(0,-2) = x2,y2

here, x1= 3, x2= 0, y1= 1, y2 = -2

By Distance Formula

d(AB) = ✓(x2 - x1)² + ✓(y2-y1)²

= ✓ (0-3)² + (-2-1)²

= ✓(-3)² + (-3)²

= ✓9+9

= ✓18

the distance between the point (3, 1) (0, -2) is ✓18
