ANSWER
The approximate solution is
Step-by-step explanation
The point of intersection of the two lines is the solution of the linear systems represented by the graph.
From the graph we can determine that each box is 2 units.
From the graph, when we start at O and count two boxes to the right and half box down, we obtain the point of intersection of the two lines to be
Note that since each box is two units, half way between the boxes gives one unit.
