What are the x and y-intercepts of 3x+2y=21?
\n" ); document.write( "Plug-in x=0 and solve for y. This will give you the y-intercept.
\n" ); document.write( "Plug-in y=0 and solve for x. This will give you the x-intercept.
\n" ); document.write( ".
\n" ); document.write( "Y-intercept:
\n" ); document.write( "3x+2y=21
\n" ); document.write( "3(0)+2y=21
\n" ); document.write( "2y=21
\n" ); document.write( "y=21/2
\n" ); document.write( "(0, 21/2)
\n" ); document.write( ".
\n" ); document.write( "x-intercept:
\n" ); document.write( "3x+2(0)=21
\n" ); document.write( "3x=21
\n" ); document.write( "x=7
\n" ); document.write( "(7, 0)\r
