For most of these you need to remember that something that looks like (1,2) is really saying x=1, y=2. Half the problems you posted can be solved if you just substitute the given value(s) into the given equation.

For the second half of the questions, remember that the equation for a line looks like:
y=mx+b
so if you can move terms around to get it into this form then it is a linear equation.
For example:
8b+4c=-2 (assuming b is the independent variable and c is the dependent variable)
subtract 8b from both sides
4c=-8b-2
divide both sides by 4
c=-2b-0.5
now this looks like y=mx+b so it is a linear equation.

Hope this helps, ask questions if you don't understand something.

For future, more people will be able to help you if you post in the mathematics section, or science & maths section in "homework help".

I don't really check the highschool section, and i dont know how many people do

I do!

Yeah but you're silly.
