2. For number 3 and 6, you can simply test solutions by substituting each of the x and y coordinates for x and y in the equation.

4. #3 since y increases by 3 when x increases by 1, the slope is 3/1 = 3.
Only one choice has a slope of 3.

And, as Leo said, you can just plug in the x's and see whether the y's match!

#4 ok
#5 ok
#6 looks like A to me. Did you even try the given points?
#7 ok
#8 ok

You did ok, for the ones where you provided an answer.
