The coordinates of the midpoint are the average of the coordinates of the given points.
So, the x coordinate of the midpoint is the average of the x coordinates of the given point:

And similarly, the y coordinate of the midpoint is the average of the y coordinates of the given point:

So, the midpoint is the point

I don’t know how to explain but hope this helps.
The variables x and y vary inversely. When y is 5 x is 3, so when y is 15 x is 9.
Y = 0x + 3
