(-5,3) and (-5, 11)
6 units

(-20, -18) and (-22, -21)
8 units
D.
(-2, 4) and origin
15 units
E.
(7.-8) and (-2,-20)
Which of the following is correct sequence of the matching?

A = 6 units, B = 8 units, C = 3.6 units, D = 4.5 units, E = 15 units

Step-by-step explanation:

A and B can be solved by inspection, as they have a co-ordinate that is the same: A (-3;4) and (3;4) has the same y-coordinate, so the distance between the points can be measured by the difference in their x-coordinates; B (-5;3) and (-5;11) has the same x-coordinates, so the distance can be measured by the difference in their y-coordinates.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
