Question

The distance between the points (1,8) and (4,4) is equal to 5

Answer 1

TRUE OR FALSE

Answer 2

\[ D = \sqrt{(x_2 - x_1)^2 - (y_2 - y_1)^2}
sqrt((4-1)^2 + (4-8)^2)
= sqrt((3)^2 + (-4)^2)
= sqrt(9 + 16)
= sqrt(25)
= 5

true

Answer 3

\[ D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
maybe this would look better with a plus sign too

Answer 4

TY

Answer 5

Glad to help. :)
