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

$[\frac{x1+x2}{2} , \frac{y1+y2}{2}]$

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

=$\frac{0+15}{2}$

=7.5
