Question

find the length of the segment with end point (0,1) and (-3,-3)

Answer 1

having the points A(0, 1) and B(-3, -3) we then calculate AB, that is:

AB(-4, -3)

Now, using AB we will determine the length as follows:

$l=\sqrt[]{(-4)^2+(-3)^2}\Rightarrow l=5$

So, the length of the segment is 5 units.
