A recipe for punch says to use 1 3/5 cups of lemonade for each cup of ginger ale. If you use
3 2/3 cups of ginger​ ale, how much lemonade should you​ use?

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)

you would need to know all the numbers that are on there
