Algebra.Com's Answer #356864 by mathie123(224)![]() ![]() ![]() You can put this solution on YOUR website! Let's first graph the line \n" ); document.write( " \n" ); document.write( "We will put this into slope-intercept form to make this easier: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So this line looks like \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now, our graph is essentially broken up into two regions. We can take a point in each region and \"test it\". ((You can pick any points... because I like work to be easy... I will pick points on the x or y axis so I have a zero to deal with) \r \n" ); document.write( "\n" ); document.write( "For the lower region I will use (0, 0) \n" ); document.write( "so \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "This is not true, so we cannot shade this region. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For the upper region I will use (0,3) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This is true, so I can shade the upper region. \n" ); document.write( "Since \n" ); document.write( " \n" ); document.write( "Has a = to 10, the line will be solid.... if however it was just >, the line would be dotted as the region would get really close to the line but would never touch the line. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hopefully this helps, let me know if you are still unsure:) \n" ); document.write( " |
