The coordinates of the midpoint of $\overset{炉}{A B}$ isrole="math" localid="1647366699895" $(- 3, 0)$ .

Step by step solution

Step 1. Write the formula to find the coordinates of the midpoint of the line joining the points Ax1,y1and Bx2,y2.

The formula to find the coordinates of the midpoint of the line joining the points $A (x_{1}, y_{1})$ and $B (x_{2}, y_{2})$ is $(\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})$ .

Step 2. Find the coordinates of the midpoint of the line joining the points A(-3,4) and B(-3,-4).

The coordinates of the midpoint of the line joining the points $A (- 3, 4)$ and $B (- 3, - 4)$ is given by:

$\begin{matrix} (\frac{鈭� 3 + (鈭� 3)}{2}, \frac{4 + (鈭� 4)}{2}) = (\frac{鈭� 3 鈭� 3}{2}, \frac{4 鈭� 4}{2}) \\ = (\frac{鈭� 6}{2}, \frac{0}{2}) \\ = (鈭� 3, 0) \end{matrix}$
