The slope of the line is 4
The Y intercept of the line is -6
Distribute the 4:
4z - 20 + 2 = 4z - 18
Subtract 4z
-20 + 2 = -18
-18 = -18
This is true so that means there are infinite number of solutions... z could be anything!

Answer:
The number of DVD's is 6.
Step-by-step explanation:
Given:
Grace bought a television for $329.
Some DVDs for $5.75 each.
She spent total of $363.50
Now, to find out the number of DVD's Grace bought.
Let the number of DVD's be 
So, cost of DVD's =
Cost of television = $329.
Total amount spent = $363.50.
According to question:
Now, putting the equation to solve:

<em>Subtracting with 329 on both sides we get:</em>

<em>Dividing both sides by 5.75 we get:</em>

Therefore, the number of DVD's is 6.
