Question 561100
The y intercept has an x coordinate value of 0.
The x intercept has a y coordinate value of 0.

So given {{{y = -2x - 6}}}
If x =0, then {{{y = -2*(0) - 6}}}
{{{y = 0 - 6}}}
{{{y = -6}}}
Y intercept is the point (0, - 6)

When y = 0, then {{{0 = -2x - 6}}}
{{{6 = -2x}}}
{{{-6/2 = x}}}
{{{-3 = x}}}
X intercept is the point (-3, 0)
