document.write( "Question 672815: LEASE HELP I HAVE A QUIZ ON TUESDAY Okay, so lately I've been having trouble in Algebra. We're doing slopes and graphing them, and I get the basics. It's the more complicated stuff I get confused on. y = mx+b 1.) y = x^2 - 1 2.) y = 5/2x - 3 3.) 2y = 4x + 8 4.) y = 2x^2 - 6 These are all graphing equations. If you could please explain how to tackle these problems and do them successfully, I'd be really happy! Thanks! \n" ); document.write( "

1.) y = x^2 - 1 2.) y = 5/2x - 3 3.) 2y = 4x + 8 4.) y = 2x^2 - 6 These are all graphing equations.
\n" ); document.write( "----------------
\n" ); document.write( "#2 & #3 are linear, so you need 2 points.
\n" ); document.write( "---------
\n" ); document.write( "y = 5/2x - 3
\n" ); document.write( "Pick 2 values for x and find y
\n" ); document.write( "Plot the 2 points, draw a line thru them.
\n" ); document.write( "=================
\n" ); document.write( " 3.) 2y = 4x + 8
\n" ); document.write( "y = 2x+4
\n" ); document.write( "Same as #2
\n" ); document.write( "--------------
\n" ); document.write( "The other 2 are 2nd order.
\n" ); document.write( "Plot as many points as you like, then draw a smooth curve thru them.
\n" ); document.write( " \n" ); document.write( "
