Can you write this equation in function form so I can graph it?
\n" ); document.write( "15x + y = 20
\n" ); document.write( ":
\n" ); document.write( "Subtract 15x from both sides and you have:
\n" ); document.write( "y = 20 - 15x
\n" ); document.write( ":
\n" ); document.write( "Since it's linear you only have to plot a couple points, but a third point will
\n" ); document.write( "ensure that you are doing it correctly
\n" ); document.write( "Choose values for x: -1, +2, +3, find y and plot them
\n" ); document.write( ":
\n" ); document.write( "x | y
\n" ); document.write( "------
\n" ); document.write( "-1 | 35
\n" ); document.write( " 0 | 20
\n" ); document.write( "+1 | 5
\n" ); document.write( "+2 |-10
\n" ); document.write( ":
\n" ); document.write( "It should look like this:
