Question 962533
The easiest way is to find the equation of the line first then find the y-coordinate of the point.

{{{y=mx+b}}}
{{{6=(6/5)*-3+b}}}
{{{6=-18/5+b}}}
{{{b=48/5}}}

so the line has equation

{{{y=(6/5)x+48/5}}}

Substituting our given values, we get

{{{0=(6/5)x+48/5}}}
{{{-48/5=(6/5)x}}}
{{{x=-8}}}

The line will pass through (-8,0).
