pls help with #3 and #6!??
thanks

sry.....

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.

#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. 
All of these are correct, except 6 and 3, which are: 3: B. 6: Look at Steve's answer.
