Question 1179331

use point slope formula

{{{y-y[1]=m(x-x[1])}}} where {{{m}}} is a slope and {{{x[1]}}} and {{{y[1]}}} are coordinates of given point

slope  {{{m=1}}} 
passing through the point, ({{{-5}}},{{{-1}}})

{{{y-(-1)=1*(x-(-5))}}}

{{{y+1=(x+5)}}}

{{{y=x+5-1}}}

{{{y=x+4}}}-> your line


find one more point that lie on a line, plot both points and draw a line through


{{{x}}}|{{{y}}}

{{{2}}}|{{{6}}}
