Question 953495

Line s 
 {{{y=2x+2014}}}
{{{0=2x+2014}}}
{{{2x=-2014}}}
{{{x=-1007}}}

Line m has slope {{{-1}}} and the same x-intercept as line s

{{{y=-1*x+b}}} 

{{{y=-x -1007}}}

a) Find the y-intercept of line "m"

if {{{x=-1007}}} then {{{y=0}}}, substitute it and solve for {{{b}}}
{{{0=-1*(-1007)+b}}}
{{{0=1007+b}}}
{{{b=-1007}}}


b) Write the equation of line "m" 

{{{y=-x -1007}}}
