Question

Find the distance between the two points. (1, 2), (7, 6)

Answer 1

$\text {Distance = } \sqrt{(Y_2-Y_1)^2+(X_2-X_1)^2}$

$\text {Distance = } \sqrt{(6-2)^2+(7-1)^2}$

$\text {Distance = } \sqrt{(4)^2+(6)^2}$

$\text {Distance = } \sqrt{52}$

$\text {Distance = } 2\sqrt{13} \ \text { (radical form) or } 7.21 \ \text { (nearest hundredth)}$
