how do you graph x+y=3, And how do u know if its linear or not?
\n" ); document.write( "-----------
\n" ); document.write( "It's linear because all exponents are 1.
\n" ); document.write( "----
\n" ); document.write( "x+y=3
\n" ); document.write( "It's a straight line, so you need 2 points.
\n" ); document.write( "---
\n" ); document.write( "Let x = 0, solve for y --> (0,y)
\n" ); document.write( "Let y = 0, solve for x --> (x,0)
\n" ); document.write( "---
\n" ); document.write( "Plot the 2 points.
\n" ); document.write( "Draw a line thru them.
\n" ); document.write( "
\n" );
