When a point is the midpoint of a line, then the distance from (in this case) P to the midpoint Q is half the distance from P to R. To find the relevant co-ordinates, use the formula:
`M = ((x_(1) + x_(2))/2` ; `(y_(1)+y_(2))/2)` where M is the midpoint.
Care not to confuse the formula with m(slope or gradient) formula. Midpoint uses a capital M and slope/gradient a lower case m.
Substitute the values of the co-ordinates at P and at R and it will render the co-ordinates at Q.
Ans: If Q is the midpoint of PR, PQ= `(PR)/2`
