Manuel builds and sells wooden crates. He made this table to show how much his crates cost in dollars.

2 answers:

7 0

The difference between the costs is $20 and the difference in the crates is 2 so the slope is 20/2=10, the coefficient for x.
The equation then is y-k=10(x-h) where (x,y) is a pair of values from the table: (2,25), (4,45), (6,65), (8,85). Eliminate answers A and C because the coefficient is -10. Answer D has the (h,k) values the wrong way round, but B is correct in all respects so B is the answer.

Hello there!

First of all, find the slope of the right side of the graph. The slope is 2. So far we have:
y=2

Now look at the x coordinate of the point. Now we have:
y=2|x-0|
y=2|x|

Next the graph is shifted down 2 so add a negative two.
y=2|x|-2

I hope this helps!
Best wishes.
