Are the given solutions correct? And are what I worked the right answers? If not, please tell me where I made a mistake. I'm not too sure if I substituted the y values correctly...

Your answer is correct, you can also test your results by subbing them into the original equation.

Spoiler:

For (-5,2) : which is correct as is so (-5,2) is a valid solution

For (11/3 , -8/9): so (11/3 , 8/9) is a valid solution.

Thanks for your clarification...! (Bigsmile)

I have another question, but I'm not too keen to start another thread topic on it seeing that the questions are related...
