2x+y=6. im trying to solve this question before i graph it and i can't remember how to do it.

So, to graph this thing, you must put it in terms of y (at least, that's convention). So, let's isolate y:



Rearrange the equation so it's easier to graph (i.e. put it in slope-intercept form):


From this, we can understand that the graph intercepts the y-axis at 6, and the slope is -2.
