Question

Find the distance between the points given.

(-1, -1) and (1, 3)

Answer 1

the distance of two points can be determined using the formula:
\[d = \sqrt{(x_2-x_1)^2 + (y_2 - y_1)^2}\]
having the points, you'll have:
y2 = 3
y1 = -1
x2 = 1
x1 =-1

Answer 2

thank you

Answer 3

i got 18

Answer 4

\[d = \sqrt{(1-(-1))^2 + (3-(-1))^2}\]
\[d = \sqrt{(2)^2 +(4)^2}\]
\[d = \sqrt{20}\]
or
\[d = 2\sqrt{5}\]
or in decimal
\[d = 4.47 units\]
