How do you graph f(x)=-5x
\n" ); document.write( "Plot 2 points and draw a line thru them.
\n" ); document.write( "If x = 0, y = -5*0 = 0
\n" ); document.write( "If x = 1, y = -5*1 = -5
\n" ); document.write( "----
\n" ); document.write( "Plot (0,0) and (1,-5) to get:
\n" ); document.write( " $\"graph%28400%2C400%2C-10%2C10%2C-10%2C10%2C-5x%29\"$
\n" ); document.write( "------------------------------------------------------------------------
\n" ); document.write( "f(x)=(1/2)x + 4
\n" ); document.write( "If x = 0, y = (1/2)*0+4 = 4
\n" ); document.write( "If x = 2, y = (1/2)2+4 = 5
\n" ); document.write( "--------------------------------
\n" ); document.write( "Plot (0,4) and (2,5) to get:
\n" ); document.write( " $\"graph%28400%2C400%2C-10%2C10%2C-10%2C10%2C%281%2F2%29x%2B4%29\"$
