You can put this solution on YOUR website!
You can solve this quite easily if you think about it. Ask yourself what the x value is
\n" ); document.write( "for any point on the y-axis. It may become clear that any point on the y-axis will have a
\n" ); document.write( "corresponding value of zero for x.
\n" ); document.write( ".
\n" ); document.write( "So in this equation all you need to do is to set the value of x equal to zero and solve
\n" ); document.write( "for the corresponding value of y.
\n" ); document.write( ".
\n" ); document.write( "The equation you were given is:
\n" ); document.write( ".
\n" ); document.write( "2x + 4y = 20
\n" ); document.write( ".
\n" ); document.write( "When you set x equal to zero, the term 2x becomes zero and therefore, it drops out. The
\n" ); document.write( "equation is then:
\n" ); document.write( ".
\n" ); document.write( "4y = 20
\n" ); document.write( ".
\n" ); document.write( "Solve for y by dividing both sides by 4 and you get:
\n" ); document.write( ".
\n" ); document.write( "y = 20/4 = +5
\n" ); document.write( ".
\n" ); document.write( "Therefore, the y intercept is the point (0, +5) and it is on the y-axis at a value of +5.
\n" ); document.write( ".
\n" ); document.write( "Hope this clarifies the problem for you and helps you to see how to do the problem.
