Question

What's the length of a segment that begins at the point (2, 3) and ends at the point (18, 15)? 

Answer 1

So first of all we need to find the slope and it will give us the answer what is the length of a segment.

To find it we are using the formula:
y2-y1/x2-x1.

15-3/18-2=12/16=3/4.
So I think that the length of the segment is 3/4 cm or what you didn’t tell it for me. Hope this helps.
