Help me solve question number 8 part a

We need to use the midpoint theorem here

[ 1 + p ] / 2 = 8

Multiply both sides by 2

1 + p = 16 subtract 1 from both sides

p = 15

And to find q, we have that

[ 7 + q ] / 2 = 2

7 + q = 4 subtract 7 from both sides

q = -3

Thanks for the answer but when u said 'the midpoint theorem' is it like x_{1}+x_{2}/2 and y_{1}+y_{2}/2 ??

Exactly....!!!!

Now it makes sense, thanks dude
