So I don't understand this, I'm doing systems of equations:

2x+5y-6=0

-2x+y-2=0

I figured out that the first equation's y-intercept will be a decimal, right? So how would you graph it to make both lines intercept at a point.

It only takes two points to plot a line. For the first eq., if y=0, x=3 and if x=0, y= 6/5 so plot those points. For the second eq., if y=0, x=-1 and if x=0, y=2. Plot those and see where the lines intersect. You can also solve the two equations simultaneously. Just add the equations to get 6y-8= 0, so y=4/3. put that in the first eq. and find x=-1/3
