Given a line:
\n" ); document.write( ".
\n" ); document.write( "\"y+=+%282%2F3%29x%2B1\"
\n" ); document.write( ".
\n" ); document.write( "This is in the slope-intercept form:
\n" ); document.write( ".
\n" ); document.write( "\"y+=+mx+%2B+b\"
\n" ); document.write( ".
\n" ); document.write( "in which m (the multiplier of x) is the slope of the line and b is the value of y at the
\n" ); document.write( "point the graph of the line crosses the y-axis.
\n" ); document.write( ".
\n" ); document.write( "By comparing the slope intercept form with the given equation you can see that in the given
\n" ); document.write( "equation \"2%2F3\" is the slope because it is the multiplier of x.
\n" ); document.write( ".
\n" ); document.write( "Any line that is parallel to the graph of \"y+=+%282%2F3%29x+%2B+1\" must have the same slope
\n" ); document.write( "as the graph. So, in the slope intercept form, the line L will have the equation:
\n" ); document.write( ".
\n" ); document.write( "\"y+=+%282%2F3%29x+%2B+b\" where b is the y-axis intercept. The problem tells you that the
\n" ); document.write( "value of y on the y-axis is -3. Substituting this for b in the equation results in the
\n" ); document.write( "equation for L becoming:
\n" ); document.write( ".
\n" ); document.write( "\"y+=+%282%2F3%29x+-+3\"
\n" ); document.write( ".
\n" ); document.write( "and this is the answer to the problem. Line L is defined by the equation:
\n" ); document.write( ".
\n" ); document.write( "\"y+=+%282%2F3%29x+-3\"
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the concept of parallel graphs ... they will have the
\n" ); document.write( "same slope, but the y-intercepts will be different.
\n" ); document.write( "
\n" );
