You can put this solution on YOUR website!
Well I have have the graphs you have to choose from.... but I will show you how you could generate this graph:\r
\n" ); document.write( "\n" ); document.write( "Let's first look at 3x – 4y = 32. We will isolate y to get it into y=mx+b form:
\n" ); document.write( "\"3x+%96+4y+=+32\"
\n" ); document.write( "\"3x-4y-32%2B4y=32-32%2B4y\"
\n" ); document.write( "\"3x-32=4y\"
\n" ); document.write( "\"3x%2F4-32%2F4=y\"
\n" ); document.write( "\"y=%283%2F4%29%2Ax-8\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "And now we will do the same thing for 5x + 2y = 10
\n" ); document.write( "\"5x+%2B+2y+=+10\"
\n" ); document.write( "\"5x+%2B+2y-5x+=+10-5x\"
\n" ); document.write( "\"2y=+10-5x\"
\n" ); document.write( "\"y=+10%2F2-%285%2F2%29%2Ax\"
\n" ); document.write( "\"y=+5-%285%2F2%29%2Ax\"
\n" ); document.write( "\"y=+-%285%2F2%29%2Ax%2B5\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Remember that once you have the lines in y=mx+b form, you have a point (0,b) for each line and then we can use the slope to get another point.
\n" ); document.write( "After graphing both lines we get:
\n" ); document.write( "\"graph%28500%2C500%2C-10%2C10%2C-10%2C10%2C%283%2F4%29%2Ax-8%2C+-%285%2F2%29%2Ax%2B5%29\"\r
\n" ); document.write( "\n" ); document.write( "This is the graph you are looking for-- notice that when you solve this system of equations, you are finding the point where these lines intersect.
\n" ); document.write( "___________________________________________________________________________
