Question 865303
For the coordinate (3, something) the three is the <b>x value</b>. Because in the equation{{{4x &#8722; 3y = &#8722;12 }}} x is the value of the coordinate, when you substitute  in the value for x, when you solve for y, it will give you the <b>y value</b>.
{{{4x-3y=-12}}}
{{{4*3-3y=-12}}}
{{{12-3y=-12}}}
Subtract 12 from both sides
{{{-3y=-24}}}
Divide both sides by -3
{{{y=8}}}
<h3>(3, 8)</h3>
For the next, ( ,-8), -8 is the <b>y value</b>
{{{4x-3y=-12}}}
{{{4x-3(-8)=-12}}}
{{{4x+24=-12}}}
Subtract 24 from both sides
{{{4x=-36}}}
Divide both sides by 4
{{{x=-9}}}
<h3>(-9, -8)</h3>
For the next coordinate, ( ,10), 10 is the <b>y value</b>
{{{4x-3y=-12}}}
{{{4x-3(10)=-12}}}
{{{4x-30=-12}}}
Add 30 to both sides
{{{4x=18}}}
Divide both sides by 4
{{{x=9/2}}}
<h3> The three coordinates are (3, 8), (-9, -8), and (9/2, 10)
