1. What is the approximate solution of the linear system represented by the graph below?
nlexa [21]

Answer:

x = 5 and y = 6; that is the (5, 6) (x, y) pair.

Step-by-step explanation:

The graph shows two lines that cross at the point (5, 6) on the plane (see attached image).

This means that the point x=5 and y=6 belongs to both lines (is a solution for both equations representing the lines) and therefore this pair of values is the solution to both equations in the system.
