Question 433071
Are you sure you copied it right? I don't see any {{{x}}},
anyway if it's correct,
{{{ y + 6 = 6 }}}
Subtract {{{6}}} from both sides
{{{ y = 0 }}}
This is the equation of the x-axis, since that
is the only line whose y component is zero
everywhere on the line.
The y-intercept is at {{{ y = 0 }}}
