Question 148817
Ellen,

What was the "equation", "graph", or problem?  We need to see that.

Based on your "subject" reference to "coordinate system", I assume you have a graph.
To find the "intercept", simply look along the y-axis.  Wherever the line crosses it, that will be your y-intercept.  AND, the coordinates for x HAS to be 0.  Therefore, I would suspect that your coordinates are (0,-6)

Regards,
Bill
