Describe a Graph.

(A). Describe what the graph of a system of equations looks like when it has:

(1). 1 solution.

(2). 0 solutions.

(3). Infinitely many solutions.

Use the applet to confirm your answer.

(B). The graphs of the equations += 15 and + = 9 intersect at (2, 1). Find and .Show or explain your reasoning on the applet below.
