Question

use the distance formula to find the distance between w(-1,4) and t(4,1)

Answer 1

The formula of a distance between two points:

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

We have the points W(-1, 4) and T(4, 1). Substitute:

$d=\sqrt{(4-(-1))^2+(1-4)^2}=\sqrt{5^2+(-3)^2}=\sqrt{25+9}=\sqrt{34}$
