I assume the \"x2\" in examples 8-10 is supposed to be \"x squared\".  Use \"^\" to denote an exponent -- e.g. \"-4x^2\" instead of just \"-4x2\".<br><BR>\n" );
document.write( "Since examples 8-10 all contain an \"x^2\", they are not linear.<br><BR>\n" );
document.write( "(2) If the equation is linear and you want to find the slope and y-intercept, you need to put the equation in slope-intercept form, y=mx+b (or, in your notation, f(x) = mx+b).  In particular, in examples 6 and 7 you need to get rid of the parentheses before you can find the slope and y-intercept.<br><BR>\n" );
