doomgaze thanks, im having trouble on how the graph should look for

y+2x=2 - Apr 2nd 2010, 08:18 PMdoomgaze
Like I said, the best way to start is to make it a lot easier on yourself and solve so that your function has y by itself. y=

so y=2-2x or y=-2x+2 <-- this one is in perfect form of Y=mx+b

Since b=2 you know it's going to intersect the y-axis at the point (0,2) and then you use the slope m=-2/1 so you move 2 on the y-axis and then 1 on the x-axis

The graph looks like this:

Most important, do you understand what I did? - Apr 2nd 2010, 10:33 PMmr fantastic

The point is- that is a linear function so its graph is a straight line. Choose any two points on that line- the intercepts mr. fantastic chose are particularly easy- and draw the line through them.
