Yes?

Answer 10

5 = ( 6 + y)/2 how would i find the formula he gave me

Answer 11

the midpoint... is simply the average of the x values and average of the y values.

There is a formula... but it's easier to remember average x and average y

so add the 2 values and divide the answer by 2

hope it makes sense
