Question 1187094


{{{y=-x-5}}}

Find four points contained in the inverse. Express your values as an integer or simplified fraction.

first find the inverse

{{{y=-x-5}}}......swap {{{x}}} and {{{y}}}
{{{x=-y-5}}}..........solve for {{{y}}}
{{{y=-x-5}}}
so, inverse {{{y}}}'={{{-x-5}}} is same as given function

An arbitrary set of {{{4}}} points could be for {{{y}}}={{{-1}}}, {{{0}}}, {{{1}}},{{{ 3 }}}

{{{-1}}}'={{{-x-5}}}->{{{x=-4}}} 
{{{0}}}'={{{-x-5}}}->{{{x=-5}}}
 {{{1}}}'={{{-x-5}}}->{{{x=-6}}} 
{{{3}}}'={{{-x-5}}}->{{{x=-8}}} 
{({{{ -4}}} , {{{-1}}} ), ({{{-5 }}} , {{{0}}} ), ({{{-6 }}} , {{{1}}} ), ( {{{-8}}} ,{{{3}}}  )}
