Question

What is the distance between the points (2,7) and (-8,1)

Answer 1

Step-by-step explanation:

Given points ( 2 , 7) and ( - 8 , 1 )

Distance between two points

$\sqrt{(x2 - x1 )+( y2 - y1)}$

$\sqrt{(2 + 8) + (7 - 1)}$

$\sqrt{10 + 6}$

$\sqrt{16}$

$\sqrt {4}^{2}$

Therefore distance between two points is 4 units.
