Graph is attached.
Based on the graph (with height on the independent axis and weight on the dependent), there is a negative correlation between height and weight; as the height increases, the weight decreases.
If we were to graph this with weight on the independent axis and height on the dependent, there would still be a negative correlation.

The two pieces are continuous for every
So, our only concern is to make sure that the pieces "glue" continuously at x=7.
To ensure this, we evaluate both pieces at x=7, and impose that the two values are equal.
The first piece evaluates to
The second piece evaluates to
So, we want
We move all terms involving c to the left hand side, and all the numerical constants on the right hand side:
