I know it's hard to believe the answers are literally ABCD but I'm looking at it right now. Take the quick check and see for yourself.

To find the graph of the system of inequalities, we can start by graphing each inequality separately.
1. Graphing y ≤ x + 4:
- First, graph the line y = x + 4. This line has a slope of 1 and y-intercept of 4, so you can plot these two points and draw a line through them.
- Since the inequality is "less than or equal to," we will include the points on the line as part of the solution. So, the line should be drawn as a solid line.
- Since y is less than or equal to x + 4, shade the region below the line to represent all the points that satisfy the inequality.
2. Graphing 2x + y ≤ -4:
- First, graph the line 2x + y = -4. This line has a slope of -2 and y-intercept of -4, so you can plot these two points and draw a line through them.
- Since the inequality is "less than or equal to," we will include the points on the line as part of the solution. So, the line should be drawn as a solid line.
- Since 2x + y is less than or equal to -4, shade the region below the line to represent all the points that satisfy the inequality.
The graph of the system of inequalities will be the overlapping shaded region from both inequalities. The points that fall within this shaded region will satisfy both inequalities simultaneously.
