Answer:

In △PQR,

P=(2,1)

Q=(−2,3)

R=(4,5)

Mid-point of PQ=(2x1+x2,2y1+y2)=(22−2,21+3)=(0,2)

Equation of the median through the vertex R is the equation of the line passing through the points (0,2),(4,5)

Since, two points form of the line is y−y1=(x2−x1y2−y1)(x−x1)

∴ Equation of the median is

y−2=(4−05−2)(x−0)

⟹4(y−2)=3x

⟹4y−8=3x

3x−4y+8=0 (Ans)
