Inequalities
We have the inequality
5x + 3y < -6
It's required to find if the point (3,-7) is a solution to the inequality
Substituting into the inequality:
5(3) + 3(-7) < -6
15 - 21 < -6
-6 < -6
Since the inequality is false, the point is not a solution to the inequality
It's important to notice the point lies on the line since both sides are equal. The inequality does not include the equal sign, but the point does not lie on any shaded region or outside of it.
We don't have any graph to choose options from, but the correct answer is:
No - because the point falls on the line, and since the line is solid it is equal to...
