Answer:
First one: yes
Second one: yes
Third one: no
Step-by-step explanation:
To find the midpoint of a line segment, you take the x and y coordinates of the 2 points, add each of them up, and divide each of them by 2.
First one: x = (1+3)/2 = 2, y = (2+4)/2 = 3, so it's correct.
Second one: x = (-1+3)/2 = 1, y = (1+-1)/2 = 0, so it's correct.
Third one: x = (-3+-1)/2 = -2, y = (0+5)/2 ≠ 2, so it's not correct.
I really hope this helped.
