You can put this solution on YOUR website!
The equation you are given is:
\n" ); document.write( ".
\n" ); document.write( " $\"y+=+4x+-+5\"$
\n" ); document.write( ".
\n" ); document.write( "The general form of this equation is:
\n" ); document.write( ".
\n" ); document.write( " $\"y+=+mx+%2B+b\"$
\n" ); document.write( ".
\n" ); document.write( "This is called the slope-intercept form. The value of m, the multiplier of the x term, is the slope of the graph, and the value of b is the value on the y-axis where the graph crosses the y-axis.
\n" ); document.write( ".
\n" ); document.write( "So looking at the given equation, by inspection you can tell that the slope of the graph is +4 because that is the multiplier of the x term. (And also by inspection you can tell that the graph crosses the y-axis at the y value -5.)
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to recognize and use the slope-intercept form of equations.
