Question

Which methods could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0,0) and (0,15)

Answer 1

The mid point of a line with end points (x₁,y₁) and (x₂,y₂) is given by the formula

`[(x1+x2)/(2) , (y1+y2)/(2)]`

Here we only need the y coordinate hence lets calculate the y coordinate alone

=
`(0+15)/(2)`
