In this question D is origin. As co-ordinate of E(-50,0) then how co-ordinate of M is (-40,10) can be possible. Also I verified that co-ordinate of M is (-60,10) and M is also lie on line segment EF and M(-60,10) also satisfied the equation of line EF.
According to me ans should be (-60,10) but here given answer is (-40,10).
Please check.
