what is x-intercept of the line passing through points (-4,15) and having a slope of -1
\n" ); document.write( "equation of a line in slope-intercept form: y=mx+b, m=slope,b=y-intercept
\n" ); document.write( "y=-x+b
\n" ); document.write( "solve for b using given coordinates(4,15) on the line
\n" ); document.write( "b=y-x=15-4=11
\n" ); document.write( "equation: y=-x+11
\n" ); document.write( "y-intercept=11
\n" ); document.write( "
\n" );
