Find the intercepts.
\n" ); document.write( "Plot them, then connect them with the line.
\n" ); document.write( "To find the x-intercept, set \"y=0\" and solve for \"x\".
\n" ); document.write( "\"3x%2By=7\"
\n" ); document.write( "\"3x%2B0=7\"
\n" ); document.write( "\"3x=7\"
\n" ); document.write( "\"x=7%2F3\"
\n" ); document.write( "(\"7%2F3\",\"0\")

\n" ); document.write( "Typically parallel lines have identical slopes.
\n" ); document.write( "However in this case, the slope for \"x%2B2=0\" or \"x=-2\" is undefined.
\n" ); document.write( "It is a vertical line and cannot be represented with the slope intercept form, \"y=mx%2Bb\".
\n" ); document.write( "It has the form \"x=a\" and since it passes through the point (-1,0), it has the exact form of \"x=-1\".
