Question 940444
If you have multiple lines, put them all on one graph. 
So, plot {{{y=x+1}}} and {{{y=2x-3}}} using one coordinate system would be like this,
{{{graph(300,300,-10,10,-10,10,x+1,2x-3)}}}
.
.
.
but using separate coordinate systems it would look like this.
.
.
.
{{{graph(300,300,-10,10,-10,10,x+1)}}}
.
.
.
{{{graph(300,300,-10,10,-10,10,2x-3)}}}
