Question

please give me full solution

Answer 1

let us consider, the coordinate of P as x₁ and y₁ and the coordinates of Q as x₂ y₂.
coordinates on y axis are always of the form (0, y) and coordinates on x axis (x, 0).
so to find the coordinate, we will use midpoint formula.
x= x₁+x₂/2                                     y=y₁+y₂/2
2=0+x₂/2                                       -5=y₁+0/2
2×2= x₂                                           -5×2=y₁ 
∴x2= 4                                              ∴y1=-10
therefore the coordinates of:
P=(0,-10) &
Q=(4,0)
