Answer:
Step-by-step explanation:
First the solution to the equation
-4y = x - 18 Divide by - 4. Watch your signs.
-4y / -4 = x/-4 + 18/-4 Do the division. Notice the 18 needs to be divided by - 4 as well as the other two terms.
y = (-1/4)x - 4.5
Second the graph. See below.
Your original equation is what was graphed.
Third: The table with the points added to the graph.
Sample Calculation
x = 10
-4y = 10 - 18
-4y = - 8
y = -8/-4
y = 2
Point (10,2)
The graph on the right includes the table with 3 points plotted.

Answer:
$16.
Step-by-step explanation:
Let t represent the cost of each tree.
We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.
We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be
The total cost of purchasing 8 trees will be .
Since the total cost of the trees including the delivery was $168, so we can get an equation as:
Upon dividing both sides of our given equation by 8, we will get:
Therefore, the cost of each tree is $16.
