Question 75372
<pre>
find points on graph using the equation -x+2y=11 
how do you find the point for the graph



Just assume values of x then substitute them to the eqution -x + 2y = 11

If x = -1                  if x = 1

    -(-1) + 2y = 11        -(1) + 2y = 11
       1 + 2y = 11           -1 + 2y = 11
           2y = 10                2y = 12
            y = 5                  y = 6

You have two points (-1,5) and (1,6) now so you can now graph the equation.
Plot the two points then connect with a line

Note: you can assume as many as you can though two points can determine 
      the graph of this equation.

{{{graph (200, 200, -3, 7, -1, 12, (1/2)x + 11/2)}}}
