Question 565941
{{{-3x-y=6}}}
Equation of the line Slope intercept form
{{{y=mx+b}}}
Where m is slope of the line and b is y-intercept
Arrange the given equation according to slope intercept.
{{{-3x-y=6}}}
{{{-y=3x+6}}}
Multiply by -1 both sides of the above equation
{{{(-y)(-1)=(-1)(3x+6)}}}
{{{y=-3x-6}}}
Compare above equation with {{{y=mx+b}}}

m=-3, b=-6

Slope = -3 and y-intercept = -6
