Answer:
Part A: One.
Part B: (3, 5)
Step-by-step explanation:
Part A: A solution to a pair of equations is generally where the two functions intersect. As we can see, a graph is provided, so things are facilitated. We can see that they only intersect once, which means only one answer.
Part B: The solution, which as we have learned is where the two lines intersect, is (3, 5), as that is, again, the point of intersection.
