I need help sketching graphs when give an equation, such as, y=1/3x-1. I don't understand the steps to find out where on the graph to start.

\n" ); document.write( "You only need 2 points to graph a line.
\n" ); document.write( "---
\n" ); document.write( "Let x = 0, then y = (1/3)0-1 = -1
\n" ); document.write( "giving you point (0,-1)
\n" ); document.write( "----
\n" ); document.write( "Let x = 3, then y = (1/3)(3)-1 = 1-1 = 0
\n" ); document.write( "giving you point (3,0)
\n" ); document.write( "----
\n" ); document.write( "Plot the two points and draw a line thru them.
