You can start by finding the slope of the equation (similar to converting it to slope-intercept form).

OpenStudy (theedwardsfamily):

is it b. im still confused.

OpenStudy (mathmate):

Similar to the other one, x+3y=3 Isolate y by subtracting x 3y=3-x you can then finish off and decide which of the 4 slopes corresponds to the one you found.

OpenStudy (theedwardsfamily):

oh ok

OpenStudy (theedwardsfamily):

It looks like it makes sense to be line a.

OpenStudy (mathmate):

Exactly! Well done. It's because the slope is negative, so there is only one choice for a negative slope.

OpenStudy (theedwardsfamily):

yea, makes sense now! Thank you @mathmate ! :D
