Use the formula for the slope of a line:
\n" ); document.write( "m=\"%28y1-y2%29%2F%28x1-x2%29%29%29\"
\n" ); document.write( "m=\"%28%282-3%29%2F%281-3%29%29%29\"
\n" ); document.write( "m=\"%28-1%29%2F%28-2%29%29%29\"
\n" ); document.write( "m=\"%281%2F2%29\"
\n" ); document.write( ".
\n" ); document.write( "Use the formula for the slope-intercept equation of a line:
\n" ); document.write( "y=mx+b
\n" ); document.write( "Pick one point and plug it into the equation; plug-in the slope and solve for the b-value:
\n" ); document.write( "2=(1/2)(1)+b
\n" ); document.write( "2=1/2+b
\n" ); document.write( "2-1/2=b
\n" ); document.write( "3/2=b
\n" ); document.write( ".
\n" ); document.write( "Plug-in the value of the slope and the b-term:
\n" ); document.write( "y=1/2x+3/2
\n" ); document.write( "f(x)=1/2x+3/2\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
