Two points: (0,0),(1,2)
\n" ); document.write( " $\"m=%282-0%29%2F%281-0%29\"$ The slope is 2
\n" ); document.write( "y=mx+b
\n" ); document.write( "y=2x+b Plug in value,solve for b:
\n" ); document.write( "2=2(1)+b Subtract 2 from each side.
\n" ); document.write( "0=b
\n" ); document.write( ".
\n" ); document.write( "EQUATION: y=2x
\n" ); document.write( ". CHECK:
\n" ); document.write( "Through (0,0)
\n" ); document.write( "y=2x
\n" ); document.write( "0=2(0)
\n" ); document.write( "0=0
\n" ); document.write( ".
\n" ); document.write( "Through (1,2)
\n" ); document.write( "y=2x
\n" ); document.write( "2=2(1)
\n" ); document.write( "2=2 \n" ); document.write( "
