Answer:
Step-by-step explanation:
From the graph, we can see that the coordinate of z2 is (-4, -3) and that of z1 is (1,6) where;
![\begin{gathered} x_1=-4 \\ y_1=-3 \\ x_2=1 \\ y_2=6 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/xcjmncdxmy9vzclv8rip01peyra7sznvfc.png)
We'll go ahead and use the below midpoint formula to determine the coordinates of the midpoint of z1 and z2;
![Midpoint=((x_1+x_2)/(2),(y_1+y_2)/(2))](https://img.qammunity.org/2023/formulas/mathematics/college/r1max3v1zssunynndkq53b21mgvuansg7v.png)
Substituting the values into the above formula, we'll have;
![\text{Midpoint}=((-4+1)/(2),(-3+6)/(2))=(-(3)/(2),(3)/(2))](https://img.qammunity.org/2023/formulas/mathematics/college/rs7fs2ul2yibb4qe0if4gg5zoc7zpxalzo.png)
Let's go ahead and plot the above point on the graph;
