Well, good luck on your broken ankle!
\n" ); document.write( "Write, in slope-intercept form (y = mx+b) and graph:
\n" ); document.write( " $\"y%2B3+=+%28-1%2F3%29x\"$ Subtract 3 from both sides.
\n" ); document.write( " $\"y+=+%28-1%2F3%29x-3\"$ There's the equation in slope-intercept form.
\n" ); document.write( "The slope, $\"m+=+%28-1%2F3%29\"$ and the y-intercept, $\"b+=+-3\"$
\n" ); document.write( "To graph this, you need only two points, one of which can be found by letting x = 0 then solving for y, and then by letting y = 0 then solving for x. Then you plot these two points on your coordinate graph paper, having previously drawn your x-axis and y-axis, then join the two points with a straight line.
\n" ); document.write( " $\"y+=+%28-1%2F3%29x-3\"$ Substitute x = 0.
\n" ); document.write( " $\"y+=+-3\"$
\n" ); document.write( " $\"y+=+%28-1%2F3%29x-3\"$ Substitute y = 0.
\n" ); document.write( " $\"0+=+%28-1%2F3%29x-3\"$ Add 3 to both sides.
\n" ); document.write( " $\"3+=+%28-1%2F3%29x\"$ Multiply both sides by -3.
\n" ); document.write( " $\"-9+=+x\"$
\n" ); document.write( "The two points are:
\n" ); document.write( "(0, -3) and (-9, 0)
\n" ); document.write( "The graph will look like:
\n" ); document.write( " $\"graph%28400%2C400%2C-10%2C5%2C-5%2C5%2C%28-1%2F3%29x-3%29\"$
