Question 1186039

Function Rule:

{{{x}}}| {{{-10}}}| {{{-4}}}| {{{2 }}}|{{{8}}} |{{{14}}}
{{{y}}}| {{{80}}} |{{{62}}}| {{{44}}}| {{{26}}}| {{{8}}}

If {{{x=0}}}, what is {{{y}}}?

first find equation of the line:

a slope is: {{{m=(62-80)/(-4-(-10))=-18/6=-3}}}

{{{y-y[1]=m(x-x[1])}}}
{{{y-80=-3(x-(-10))}}}
{{{y=-3(x+10)+80}}}
{{{y=-3x-30+80}}}
{{{y=-3x+50}}}

If {{{x=0}}}, then {{{y=-3*0+50}}}=>{{{y=50}}}
