Question 249412
To determine the points
1. Make a table with two columns.  
2. Label one "x", the other "y".
3. Write an x value and solve for y using the formula {{{y=0.5x-600}}}
4. Those would be your first x and y point.
5. Do it again with another x value to obtain a second point.
6. You need at least two points to be able to draw a line in the cartesian plane
7. You may calculate more points, they would verify that you're in the right track.


Here is how the graph would look like for {{{y=0.5x-600}}}


{{{graph (500, 500, -200, 2000, -1000, 200, 0.5x-600)}}}
