Dear all,

I was attempting the question shown below but had no idea on how to proceed. I tried to sub the lines of regression into one another but to no avail. Could someone kindly give me some hints on how to proceed?

Thank you very much!

You have the two regression lines. There's one point that will lie on both of them - (\bar{x},\bar{y}) - and that is their point of intersection.

So, solving simultaneously will give you the two means.

Since you know 7 of the 8 points, can you now work out the eighth using the means?

And for those of you not living in Australia:
