Question 1205535
{{{y=2x}}} 

this is linear equation and the  graph is a line
to graph a line we need two points that lie on a line (a line is defined by two points)

first find the {{{x}}}-intercept


{{{y=2x}}} ...set {{{y=0}}}

{{{0=2x}}} 

{{{x=0}}} 

the {{{x}}}-intercept is at ({{{0}}} ,{{{0}}} )


now find one more point


{{{y=2x}}} ...set {{{x=1}}}

{{{y=2*1}}} 

{{{y=2}}} 

the point is at ({{{1}}} ,{{{2}}} )


plot these points and draw a line through


{{{ drawing( 600, 600, -10, 10, -10, 10,
circle(0,0,.15), circle(1,2,.12), 
locate(1,2,p(1,2)), locate(0.2,-0.3,p(0,0)), 
graph( 600, 600, -10, 10, -10, 10, 2x)) }}}
