find the midpoint of the line segment joining the points p1 and p2.

P1=(-1,5);P2(2,0)
M=(x,y)= ? type an ordered pair

average x = (2-1)/2 = 1/2

average y = (0+5)/2 = 2 1/2
so
(1/2 , 2 1/2)

To find the midpoint of a line segment, you can use the midpoint formula:

M = ((x1 + x2) / 2, (y1 + y2) / 2)

In this case, P1 = (-1, 5) and P2 = (2, 0).

To find the midpoint, substitute the coordinates into the formula:

M = ((-1 + 2) / 2, (5 + 0) / 2)

M = (1/2, 5/2)

Therefore, the midpoint of the line segment joining P1 and P2 is M = (1/2, 5/2).
