First, find the slope of the line:
\n" ); document.write( "Slope = m = \"%28%28-1-4%29%2F%28-4-3%29%29\"=\"%28-5%2F-7%29\"=\"%285%2F7%29\"
\n" ); document.write( ".
\n" ); document.write( "Next, use the slope-intercept form of a line: y=mx+b
\n" ); document.write( "(x, y ) = (-4, -1)
\n" ); document.write( "m = (5/7)\r
\n" ); document.write( "\n" ); document.write( "Plug-in the values:
\n" ); document.write( "y=mx+b
\n" ); document.write( "-1=(5/7)(-4)+b and solve for the b-term
\n" ); document.write( "-1=(-20/7)+b
\n" ); document.write( "-1+(20/7)=b
\n" ); document.write( "13/7=b
\n" ); document.write( ".
\n" ); document.write( "So,
\n" ); document.write( "y=(5/7)x + 13/7
\n" ); document.write( " \n" ); document.write( "
\n" );
