Explanation:
The question states that the points of intersection are the solutions of a certain equation.
Think about this for a moment.
The solutions of an equation tell you what values of the unknown cause the equation to be true. In this case, the solutions of the equation:
can be thought of as:
"The values of
In other words, the solutions of the equation will all be of the form:
If you were to plot these solutions as points on a graph, where would they be?
All the points of the form
So when the questions states:
"The points of intersection of
... you already know the value of k!
Therefore,
Explanation:
we have two graphs
the points of intersection are the solutions to
now to find the points of intersection we solve
now rearrange into the form of
