Graphing Linear Equations
The graph of a linear equation in two variables is a line (that's why they call it linear).
If you know an equation is linear, you can graph it by finding any two solutions
(x[1], y[1]) and (x[2], y[2]),
plotting these two points, and drawing the line connecting them.
Graph the equation x + 2y... | {"url":"http://hotmath.com/hotmath_help/topics/graphing-linear-equations.html","timestamp":"2014-04-17T09:34:41Z","content_type":null,"content_length":"5726","record_id":"<urn:uuid:1344f1f6-acad-4bcd-90f8-6207d75fb0eb>","cc-path":"CC-MAIN-2014-15/segments/1397609527423.39/warc/CC-MAIN-20140416005207-00544-ip-10-147-4-3... |
