We have the points R(1,3) and S(-2,6).
We have to calculate the mid point.
The mid point will have coordinates that are the average of each point's coordinate.
In this case, being M the mid point, the coordinate X will be:
![M_x=(R_x+S_x)/(2)=(1+(-2))/(2)=-(1)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/3phf2zp4adc3tizdkux6ypk6pkmk6owkr6.png)
The Y coordinate will be:
![M_y=(R_y+S_y)/(2)=(3+6)/(2)=(9)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/ayvj91tfirhcqysz53y7z7tb2vkfspkgj1.png)
The midpoint between R and S is M=(-1/2, 9/2).
