**drwls**, Saturday, May 3, 2008 at 11:10amI assume you are talking about linear (straight line) equations that can be written in the form y = mx + b

m is the slope or gradient. You don't plot it, but you can use it to plot each line on a graph. Start at the y-intercept (b) and draw a line with slope m.

The largest number of simultaneous equations that you can solve with graphing is two. The solution occurs where the lines intersect.

If you have three equations, you are really looking for a place where three planes intersect, and that is too hard to draw on a graph.
