What is the length of the line?
Choose 1 answer

Step-by-step explanation:

The distance formula is

 where x1, y1 is a coordinate and x2, y2 is another coordinate.  We don't have exact coordinates, but we could make some up.  Let's say that the endpoint of that line on the left is sitting at the origin (0, 0).  That means that the endpoint on the right is sitting at (6, 1).  Plugging those values into the distance formula:

simplifies to

and

so

Keep in mind that I didn't have to choose the 2 points that I did to get this right.  For example, if I said that the point on the left was located at (1, 3), then the point on the right would be located at (7, 4).  Plugging those into the distance formula would get you the exact same length.

x=30
