Answer:
x = 1, y = 3
Step-by-step explanation:
Use the y and substitute it into the 2nd equation. Solve for x. Then use that answer to solve for y.
The "line of best fit" is the result of a linear regression computation. If you have done that, you already know its equation.
If you have "eye-balled" the line into place, then you have to figure out its equation from points you read on the graph. We take a couple of the points to be ... (2001, 1700) and (2010, 2450)
The line through these points will have the equation
... y = (2450 -1700)/(2010 -2001)(x -2001) +1700
... y = (250/3)(x -2001) +1700
Putting x=2013 into this equation, we get ...
... y = (250/3)(2013 -2001) +1700
... = (250/3)(12) +1700
... y = 2700
The population is predicted to be 2700 in 2013.

Had you drawn your graph with a vertical grid line at 2013, you could have read the number from the graph.

Answer:
(x-4,y+8)
<em></em>
Step-by-step explanation:
Given

Translate
<u>8 units up</u>
The general rule for up translation is;

Where h is the unit translated up
In this case:

So, we have:

<u>4 units left</u>
The general rule for up translation is;

Where b is the unit translated left
In this case:

So, we have:

<em>Hence, the rule of translation is: (x-4,y+8)</em>
