find slope then slope intercept
\n" ); document.write( "know your equations $\"m=%28y-y%29%2F%28x-x%29\"$ $\"y=mx%2Bb\"$
\n" ); document.write( " $\"m=%28y-y%29%2F%28x-x%29\"$
\n" ); document.write( " $\"m=%28-1-5%29%2F%283-%28-1%29%29\"$
\n" ); document.write( " $\"m=%28-6%29%2F%284%29\"$
\n" ); document.write( " $\"m=-3%2F2\"$
\n" ); document.write( "use the slope to find the intercept
\n" ); document.write( " $\"y=mx%2Bb\"$ insert knowns for m, x, y
\n" ); document.write( " $\"-1=%28-3%2F2%293%2Bb%7D%7Dmultiply%0D%0A%7B%7B%7B-1=%28-9%2F2%29%2Bb\"$ add -9/2
\n" ); document.write( " $\"%28-9%2F2%29%2B%28-2%2F2%29=b\"$
\n" ); document.write( " $\"%28-11%2F2%29=b\"$
\n" ); document.write( "rewrite formula
\n" ); document.write( " $\"y=mx%2Bb\"$
\n" ); document.write( " $\"y=%28-9%2F2%29x%2B%28-11%2F2%29\"$
