12. What is the coordinate of its midpoint?
go look up the meaning of "context"
To find the coordinate of the midpoint, we need to have the coordinates of the two endpoints. Let's assume we have two endpoints, A and B, with coordinates (x1, y1) and (x2, y2), respectively.
The coordinate of the midpoint M can be found using the midpoint formula:
x-coordinate of M = (x1 + x2) / 2
y-coordinate of M = (y1 + y2) / 2
So, if you have the coordinates of both endpoints, substitute them into the formula to find the coordinates of the midpoint.
