You can put this solution on YOUR website!
To get the slope intercept form, you need to solve the equation for y, in other words put it into the form $\"y=mx%2Bb\"$
\n" ); document.write( ":
\n" ); document.write( " $\"3x-6y=9\"$
\n" ); document.write( " $\"-6y=-3x%2B9\"$
\n" ); document.write( " $\"y=%281%2F2%29x-3%2F2\"$
\n" ); document.write( ":
\n" ); document.write( "Now you know the slope is 1/2 and the y-intercept is -3/2
\n" ); document.write( ":
\n" ); document.write( "To graph it, you only need to plot two points. One of the points is given by the y-intercept, that is, you know the line passes through (0,-3/2). Pick a second value for x. Let's pick 1. Then at x = 1, y = 1/2 - 3/2 = -1, so the second point is (1, -1).
\n" ); document.write( ":
\n" ); document.write( "Plot the two points and connect them with a straight line. It should look like this:
\n" ); document.write( ":
\n" ); document.write( " $\"graph%28400%2C400%2C-3%2C3%2C-3%2C3%2C%281%2F2%29x-3%2F2%29\"$ \n" ); document.write( "
