Question

What is the approximate solution of the linear system represented by the graph below

Answer 1

ANSWER

The approximate solution is

$(4, - 1)$

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
$(4, - 1)$


Note that since each box is two units, half way between the boxes gives one unit.
