Which point would not be a solution to the system of linear inequalities shown below?

Anna11 [10]

Answer:

The coordinates (12,7) would NOT be a solution to the system of linear inequalities shown below.

Step-by-step explanation:

If you do the graphing and you look at all your options of coordinates, (12,7) is the only one that is not in the shaded areas or in the lines of the inequalities. Therefore, (12,7) should be the answer to that question. :)
