What is the y-intercept
150
200
250
180

250

Step-by-step explanation:

when x = 1, y = 250. That's the y-intercept

200

Step-by-step explanation:

A y-intercept happens when x is 0. In this case, x represents the number of months, so we want to know how many stamps Carly has before starting. You can see that there is a pattern: every month, the number of stamps increases by 50.

For example, from month 1-3 (2 months), it increased 100, meaning it increased 50 per month

Now that we have that information, we have to go backwards.

At 1 month, it was 250, so at 0 months (where x = 0) it has to be 250-50, which equals 200.

Therefore, the answer is 200.

Hope this helps! :)

explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
