Math Problem Statement
if one were to graph the solution to the following inequality: y > 2x + 3 which of the following coordinates would be in the region indicated by in the inequality equation above?
a. (2,2) b. (2, -2) c. (-2,2) d. (-2,-2) e. (2,3)
Solution
To solve this problem, we need to determine which of the given points lies in the region where the inequality is true.
Step 1: Understand the Inequality
The inequality describes a region above the line on a graph.
Step 2: Substitute the Coordinates into the Inequality
We will substitute each point into the inequality to see if it satisfies the condition .
-
Point (2,2): is false.
-
Point (2,-2): is false.
-
Point (-2,2): is true.
-
Point (-2,-2): is false.
-
Point (2,3): is false.
Conclusion:
The only point that satisfies the inequality is (c) (-2,2).

Tip: When graphing an inequality, remember that if the inequality is strict (i.e., or ), the boundary line is dashed. If it is non-strict (i.e., or ), the boundary line is solid.
