Question 1087261


your graph shows a line, so you need to find the equation for that line

use slope-point formula:


{{{y=mx+b}}} where {{{m}}} is a slope and {{{b}}} is y-intercept

to find {{{m}}} and {{{b}}}, choose two points on a graph:

since a line goes through origin, one point is ({{{0}}},{{{0}}})

so, plug in {{{x=0}}} and {{{y=0}}} in

{{{y=mx+b}}}

{{{0=m*0+b}}}=>{{{b=0}}}; so far equation is {{{y=mx}}}

a line also goes through the point ({{{-2}}},{{{2}}})

{{{2=m(-2)}}}

{{{m=2/-2}}}

{{{m=-1}}}

and your equation is:{{{y=-x}}}


{{{ graph( 600, 600, -10, 10, -10, 10,-x) }}}
