Question

How do you find the length of the line segment between the points (5,1) and (5,6)?

Answer 1

You may find the distance by looking directly at the disposition of your points on the Cartesian Plane as:

and you see the length that is going to be `5`.
Or you can use the analytical expression for the length of a segment:
`d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)`
`d=sqrt((5-5)^2+(1-6)^2)=5`
