Question

Given the system of inequalities, list all the points that are included in the solution to this system of inequalities:


`x + y > 4`

`- 2x + y < 3`
​

Answer 1

B, C

Explanation:

The solution space is the area to the right of the X where the lines cross. Only points B and C are in that space. Point E is on the line, but the line is not included in the solution space.

_____

The lines are drawn as though the inequality were an equation. The solution space is above the first line (which has negative slope) because y > ... indicates the solution is values of y above (>) the line.

The solution space is below the second line, which has positive slope, because y < ... indicates the solution is values of y below (<) the line.
