Answer:
B(-1,4)
Explanation:
Given: The midpoint of AB = M(0,3)
Coordinates of A = (1,2)
We substitute these values into the midpoint formula.
[tex]\begin{gathered} M(x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}) \\ M(0,3)=(\dfrac{1+x_2}{2},\dfrac{2+y_2}{2}) \end{gathered}[/tex]Equating the x-coordinates, we have:
[tex]\begin{gathered} \dfrac{1+x_2}{2}=0 \\ 1+x_2=0 \\ x_2=-1 \end{gathered}[/tex]Equating the y-coordinates, we have:
[tex]\begin{gathered} \dfrac{2+y_2}{2}=3 \\ 2+y_2=6 \\ y_2=6-2 \\ y_2=4 \end{gathered}[/tex]The coordinates of B are (-1,4).
