Answer:

Step-by-step explanation:
We have the equation
.
The ordered pairs of this equation have the form 
Where x is the independent variable and y is the dependent variabe.
That is, the points belonging to the line
have the form 
For
.
So, we need to find
for x_0 = -3.
Then we substitute x = -3 into the equation and clear the value of y.

.
Then the ordered pair is:

5 3/4 -4 1/10
= 23/4 -41/10
= 115/20 -82/20
= 33/20
= (20+13)/20
= 20/20+ 13/20
= 1+ 13/20
= 1 13/20
The final answer is 1 13/20~
$168 - (8 times $5)=
$168 - $40 =
$128 = 8 trees
1 tree = $128 divided by 8=
1 tree = $16
