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.

Which description matches the graph of the inequality y ≥ |x + 2| – 3? a shaded region above a solid boundary line a shaded regi
Alex777 [14]
The given inequality is y ≥ |x + 2| -3.

This inequality may be written two ways:
(a) y ≥ x + 2 - 3
    or
    y ≥ x - 1

(b) y ≥ -x -2 - 3
    or
     y ≥ -x - 5

A graph of the inequality is shown below. The shaded region satisfies the inequality.

Answer: A shaded region above a solid boundary line.

Round each mixed number to the nearest whole number. Then, estimate the quotient.
Anni [7]
You would round up because 24 16/17 is closer to 25 and 4 8/9 is closer to 5. 
which would be 25/5 which estimates to 5.

Xavier is x years old and Yvonne is y years old. Yvonne is 7 years older than Xavier. Four times Yvonne’s age is equal to 200.
Anit [1.1K]
A) y=x+7
B) y=200/4=50
C) y=x+7 and we know that y=50 so we have 50 = x+7 which can be changed to x=50-7=43

Due Today :( Please Help! show Work! Is the relation below a function? (1, 3), (-4, 0), (3, 1), (0, 4), (2, 3) Why or Why not? N
Sliva [168]
<span>Since each x value maps to one and ONLY ONE y value, this means that this given relation is indeed a function. 
The domain is defined as, "</span> The domain<span> is the set of all possible x-values which will make the function "work", and will output real y-values." so I'm guessing the domain would be 1, 3, and 2 since they are independent integers that are positive. The range would be y<4, since the range is the spread of the possible y values. I hope this helps you out. </span>
