AS MATHS PART 2

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 ??
