Question 689333

Point-slope form of {{{y=-(x+4)}}} is 

{{{y=-1*x+4(-1)}}}

{{{y=-x-4}}}

compare to point-slope form {{{y=mx+b}}}, you have a slope {{{m=-1}}} and {{{y-intercept }}}{{{b=-4}}} which is a point ({{{0}}},{{{-4}}})

we also can find {{{x-intercept }}} if we set {{{y=0}}}:

{{{0=-x-4}}}

{{{0+x=-x+x-4}}}

{{{x=-4}}}
