Question

The graph shows two lines, A and B.

Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer. (5 points)

Part B: What is the solution to the equations of lines A and B? Explain your answer. (5 points)

Answer 1

Part A.

A solution to the two equations is a point that is on both lines. That point is the point of intersection of the lines. There is one point of intersection of the lines, so that point is the solution.

Answer: There is 1 solution.

Part B.

The solution is the point of intersection of the lines. We see where the lines intersect, and we read the point of intersection of the graph. The point of intersection is (4, 4).

Answer: (4, 4)

Answer 2

Hello!

The solution is where the lines intersect. As you can see, they only intersect at one point.

A) It as one solution.

To find our solution, we just see what the point is they intersect at.As you can see, they intersect at (4,4).

B) (4,4)

I hope this helps!
