Question 714816


set {{{y=0}}} to find the {{{x-intercept}}}: 

{{{0=3x}}}

{{{0=x}}}

and set {{{x=0}}} to find the {{{y-intercept}}}: 

{{{y=3*0}}}

{{{y=0}}}

so, the {{{x-intercept}}} and the {{{y-intercept}}} are both at origin

see it on a graph:

{{{ graph( 600, 600, -10, 10, -10, 10, 3x) }}}
