Can you provide me step-by-step illustration so I might be able to use it as a guideline to complete and understand my college homework \n" ); document.write( "

$\"+y+=+x+%2B+3+\"$
\n" ); document.write( "This is in the slope-intercept form which is
\n" ); document.write( " $\"+y+=+m%2Ax+%2B+b+\"$
\n" ); document.write( " $\"+m+\"$ = slope
\n" ); document.write( " $\"+b+\"$ = y-intercept
\n" ); document.write( "All the $\"+b+\"$ does is shift the straight line
\n" ); document.write( "up or down and does not affect the slope, $\"+m+\"$
\n" ); document.write( "------------
\n" ); document.write( "To show this, I will graph 3 lines:
\n" ); document.write( " $\"+y+=+x+%2B+3+\"$
\n" ); document.write( " $\"+y+=+x+%2B+1+\"$
\n" ); document.write( " $\"+y+=+x+-+6+\"$
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-5%2C+5%2C+-8%2C+8%2C+x+%2B+3%2C+x+%2B+1%2C+x+-+6+%29+\"$
\n" ); document.write( "Now I'll keep $\"+b+\"$ the same and vary the slope, $\"+m+\"$
\n" ); document.write( " $\"+y+=+x+%2B+3+\"$
\n" ); document.write( " $\"+y+=+2x+%2B+3+\"$
\n" ); document.write( " $\"+y+=+-5x+%2B+3+\"$

\n" ); document.write( "Notice that the y-intercept at (0,3) remains fixed
