You can put this solution on YOUR website!
This is a trick question. This is a special case. Any time you have x=k, where k is a real number, and there is no y you have a vertical line going through k.
\n" ); document.write( "Vertical lines have undefined slopes.
\n" ); document.write( "x=0 can BE the y-axis, but no vertical line can cross the y-axis.
\n" ); document.write( ":
\n" ); document.write( "Find the slope and y-intercept.
\n" ); document.write( " x = –7
\n" ); document.write( "Is a vertical line going through x=-7.
\n" ); document.write( "It has an undefined slope and no y-intercept.
\n" ); document.write( "Happy Calculating!!!
