Just did my gen maths HSC n we don't do these
I haven't done them since year 9 and 10 but i will give it a go
I think if your having trouble you may be getting your x's and y's mixed up

When they give you coordinates it is (x,y) , (x,y)

thus. for the first question: (3,8) , (7,2)

would be (3+7) , (8+2)

then just sub into formula

Please correct me if i'm wrong haven't done them 4 a long time. Hope it helps

Nah haven't got my results back yet, but the exam was very easy so hopefully i didn't make too many silly errors and can pull off a band 6
