Graphing the system of equations is shown in figure attached.
Solution set is (2,-4). The lines will intersect at (2,-4)
Step-by-step explanation:
We need to graph the system of equations. 
First we will find value of x and y
Let:

Add eq(1) and eq(2)

Putting value of x in eq(1) and finding y

So, y=-4

You would reorder the terms to 2x = 22 and divide 22 by 2 which would be 11
Mark can make 303,030 birthday cakes.
The answers are 2. B, 3. D, 4. C, and 5. A.
Step-by-step explanation:
Step 1:
For question 2. 
We subtract both sides by 4 to get

For question 3.
.
We divide the entire equation by 4 to get

Step 2:
For question 4. 
We multiply both sides by 4 to get


For question 5. 
We add 4 to both sides to get


So the answers are 2. B, 3. D, 4. C, and 5. A.
Answer:
A
Moving to the right is increasing x, which means y has to decrease for negative slope
