Question

Can someone help me wit this? ASAP PLZ

Answer 1

Try this solution:

1) given (3;9) and (-8;1).

The midpoint: ([3-8]/2;[9+1]/2) = (-2.5;5).

2) given (9;9) and (2;1).

The midpoint: ([9+2]/2;[9+1]/2) = (5.5;5).

3) given (-9;9) and (-6;10).

The midpoint: ([-9-6]/2;[9+10]/2)= (-7.5;9.5).

4) given: (-9;-1) and (-4;-1).

The midpoint: ([-9-4]/2;[-1-1]/2)= (-6.5;-1).

5) given (-4;-5) and (5;-3).

The midpoint: ([-4+5]/2;[-5-3]/2) = (0.5;-4).

6) given (-3;5) and (4;5).

The midpoint: ([-3+4]/2;[5+5]/2)= (0.5;5).

7) given (-1;1) and (4;4).

The midpoint: ([-1+4]/2;[1+4]/2)= (1.5;2.5).

8) given (-4;-2) and (5;-3).

The midpoint ([-4+5]/2;[-2-3]/2)= (0.5;-2.5).

The formula of a midpoint:

$(\frac{x_a+x_b}{2} ; \frac{y_a+y_b}{2} ).$
