Question

The number of crates c(w) in a warehouse is a function of the number of weeks w since a new shipping contract was signed, as shown in the table. The function is a linear function.

What does the y-intercept of the function represent?
There were 12 crates in the warehouse when the new shipping contract was signed.
There were 36 crates in the warehouse when the new shipping contract was signed.
Twelve weeks after the new contract was signed, all the crates were shipped out.
Thirty-six weeks after the new contract was signed, all the crates were shipped out.

Answer 1

hi

Answer 2

Haha hiii :) Sorry this took me a sec!
So a normal ordered pair is (x,y) right?
y-intercepts are shown like (0,y)
So in this case, the w is treated like x, and c(w) is y.
So if you look where the w is at 0, the value under it is the y-intercept.
Make sense? So it's 36 crates

Answer 3

And no time has passed, so it'd have to be the second choice :)
Hope that helps!

Answer 4

omg yes it does but so if i ever see a number under zero that will always be my y intercept? thank you so much!

Answer 5

Yes, and if zero is on the bottom, the number on top is the x-intercept!
And sometimes the tables are vertical, don't let that mess you up lol that just means x is on the left and y is on the right

Answer 6

haha wow :)!!!
