and has the red line as its graph:

{{{drawing(200,200,-4,4,-4,4,graph(200,200,-4,4,-4,4,x),circle(1,1,.075))}}}

The graph of y = 2x passes through (0,0) and (1,2)
and has the green line as its graph:

{{{drawing(200,200,-4,4,-4,4,graph(200,200,-4,4,-4,4,x,2x),circle(1,1,.075),circle(1,2,.075))}}}

The graph of y = 3x passes through (0,0) and (1,3)
and has the dark blue line as its graph:

{{{drawing(200,200,-4,4,-4,4,graph(200,200,-4,4,-4,4,x,2x,3x),circle(1,1,.075),circle(1,3,.075),circle(1,1,.075),circle(1,2,.075))}}}

The graph of y = {{{1/2}}}x passes through (0,0) and (2,1)
and has the baby blue line as its graph:

{{{drawing(200,200,-4,4,-4,4,graph(200,200,-4,4,-4,4,x,2x,3x,10,11,x/2),circle(1,1,.075),circle(1,2,.075),circle(1,3,.075),circle(2,1,.075))}}}

The graph of y = {{{1/3}}}x passes through (0,0) and (3,1)
and has the purple line as its graph:

{{{drawing(200,200,-4,4,-4,4,graph(200,200,-4,4,-4,4,x,2x,3x,10,11,x/2,x/3),circle(1,1,.075),circle(1,2,.075),circle(1,3,.075),circle(2,1,.075),circle(3,1,.075))}}}
