Question

1. Find the distance between (-1, 1) and (3, 4)

Answer 1

Answer:

$d=5$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in the 2 coordinates into the distance formula to find distance d:

$d=\sqrt{(3-(-1))^2+(4-1)^2}$

$d=\sqrt{(3+1)^2+(3)^2}$

$d=\sqrt{(4)^2+9}$

$d=\sqrt{16+9}$

$d=\sqrt{25}$

$d=5$
