SOLUTION: Make a table and graph x+y=1.

Make a table and graph x+y=1.



Assume values of x and substitute them to the equation to find y.



Let x = -2              x = 0            x = 2

  x + y = 1            x + y = 1        x + y = 1

  -2+ y = 1            0 + y = 1        2 + y = 1 

      y = 1 + 2            y = 1            y = 1 - 2

      y = 3                                 y = -1





HEre is the table.



            x      |         y

           -2      |         3

            0      |         1

            2      |        -1



Plot the three points. Draw a line passing through the three points.

Here is the graph
