You can put this solution on YOUR website!
First, recognize that this is the equation of a line. The x-intercept is defined as the point on the line where y=0. So, set y to zero in the equation, solve for x, and you are done:
\n" ); document.write( " $\"4x%2B12=3y\"$
\n" ); document.write( " $\"4x%2B12=0\"$
\n" ); document.write( " $\"4x=-12\"$
\n" ); document.write( " $\"highlight%28x=-3%29\"$
\n" ); document.write( "The y-intercept is defined as the point on the line where x=0. To find this point, set x to zero in the equation, solve for y, and you are done:
\n" ); document.write( " $\"4x%2B12=3y\"$
\n" ); document.write( " $\"12=3y\"$
\n" ); document.write( " $\"highlight%28y=4%29\"$
