Hello there.

Question: <span>Mr. Nicolas is putting up strings of blue and white lights for the holidays. The ratio of blue to white lights is 5 to 6. If he has 77 strings, how many strings are white lights?

Answer: 5:6

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.
