3. A student tries to push refrigerntor magnets together. These magnets have one side
covered in plastic animal faces and the other side exposed. He notices that the exposed
sides of the magnets repel each other even though they stick to the refrigerator. Which of
the following statements would be true?

Step-by-step explanation:

they won't stick together because there sides are opposite

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)
