Marcy
The school and Marcy are on the same x axis on the grid at -3 whilst Henry is the opposite end of the axis. Thus on the x axis Marcy is closer
On the y axis Henry is closer as they are both on 8 and Marcy is on 2
However overall Marcy is closer as the difference between -3 and 4 is 7 and the difference between 2 and 8 is 6
Hope this is right And hope it helps!
