Someone please help me on this I’ll make you brainlist
mamaluj [8]

Answer:

M = (1,-2)

Step-by-step explanation:

The coordinates of the midpoint is the "average" of the x points and y points of the two coordinates given.

Given:

S = (-1,1)

T = (3,-5)

To find x coordinate of Midpoint M, we take average of both x coordinates of points S and T:

(-1+3)/2 = 1

To find y coordinate of Midpoint M, we take average of both y coordinates of points S and T:

(1-5)/2 = -2

So, the Midpoint M is:

M = (1,-2)
