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

 

Multiply both sides by 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 x1+x2/2 and y1+y2/2 ??
