Step 1: Write out the coordinate of the midpoint


M(-2,-3)

Step 2: Find the coordinates of the two line segments by testing for values that will yeild the midpoint coordinates


\begin{gathered} \text{ Since the midpoint M is at (-2,-3), then} \\ M(-2,-3)\Rightarrow(x_m,y_m) \\ x_m=(x_1+x_2)/(2)=-2 \\ y_m=(y_1+y_2)/(2)=-3 \end{gathered}
\begin{gathered} \text{Thus,} \\ x_1+x_2=-2(2)=-4 \\ y_1+y_2=-3(2)=-6 \end{gathered}

From the above, we can deduce to four values that will give -4 for the x-values and -6 for the y-values.


\begin{gathered} \text{For the first line segment},\text{ say line AB} \\ x_1+x_2=-6+2=-4,x_1=-6,x_2=2 \\ y_1+y_2=-9+3=-6,y_1=-9,y_2=3 \\ \text{Therefore, line AB coordinate is } \\ A(-6,-9),B(2,3) \end{gathered}
\begin{gathered} \text{For the first line segment},\text{ say line CD} \\ x_1+x_2=-10+6=-4,x_1=-10,x_2=6 \\ y_1+y_2=-14+8=-6,y_1=-14,y_2=8 \\ \text{Therefore, line AB coordinate is } \\ C(-10,-14),D(6,8) \end{gathered}

Step 3: Draw the two lines segment on a cartesian plane showing M as the common midpoint.
