Answer:
See Below
Step-by-step explanation:
To graph y ≥ 2, draw the line y = 2 and then shade above it and keep it a solid line because the sign is "≥". (This is the red inequality on the graph.)
To graph x ≤ -1, draw the line x = -1 and then shade to the left of it and keep it a solid line because the sign is ≤. (This is the blue inequality on the graph.)
The solution set to this system will be the area where the two shaded regions overlap, which is the purple area on the graph below. Hope this helps!

Answer:
We conclude that (4, 2) is NOT a solution to the system of equations.
Step-by-step explanation:
Given the system of equations
Important Tip:
- In order to determine whether (4, 2) is a solution to the system of equations or not, we need to solve the system of equations.
Let us solve the system of equations using the elimination method.
Arrange equation variables for elimination
Subtract the equations
Now, solve -2x = 6 for x
Divide both sides by -2
Simplify
For y - x = -2 plug in x = -3
Subtract 3 from both sides
Simplify
The solution to the system of equations is:
(x, y) = (-3, -5)
Checking the graph
From the graph, it is also clear that (4, 2) is NOT a solution to the system of equations because (-3, -5) is the only solution as we have found earlier.
Therefore, we conclude that (4, 2) is NOT a solution to the system of equations.
