Question

What is the solution for the two lines given in the graph?

• A. x = -3, y = 9
• B. x = -3, y = -9
• C. x = 9, y = -3
• D. x = -9, y = -3

Answer 1

The correct option is B x = -3, y = -9

As shown in the graph, the point of intersection of the two lines is at (-3, -9). Hence the solution of the two lines is x = -3, y = -9 as solution for any pair of lines is defined as their point of intersection.
