Graphing a line is pretty easy however you do it. If we start from slope intercept form y=mx+b, we immediately know (0,b) is on the line. That's the y intercept. From that point we can use the slope to plot the line. A slope that's a fraction a/b means a units up for every b units to the right, so we can get the next point and connect the dots.
Making a table works well too. We only need two points to draw a line between them.
I guess the table might be easier when the slope is complicated, because then drawing a line at that slope might not be so easy. It's pretty easy either way so I don't know.
