What is the distance of this line?<br><br>Which is the right answer?

Shtirlitz [24]

Answer:

Step-by-step explanation:

We can use the distance formula derived from the Pythagorean theorem

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

the two points given are

(0, 3) and (-2, -3)

$(x_2-x_1) = (0-(-2)) = 2\\(y_2-y_1) = (3-(-3)) = 6\\D = \sqrt{(2)^2 + (6)^2} \\D = \sqrt{4 + 36} \\D = \sqrt{40} = 6.324$
