Answer:
D
Step-by-step explanation:
because youe last number is 90
14 because - 11-17=-28. If you divide -28 by -2x you get 14
Answer:
The slope of the line is
.
Step-by-step explanation:
We are given two coordinate points:
We are asked to find the slope of the line.
We can use the rise-over-run formula to solve for the slope of the line.

However, we firstly need to name our coordinate points.
In math, we can label our coordinates using the following label system:

Therefore, we can also label our coordinates as such:
Now, we can supply these values into the formula and solve for our slope, or a better known variable, <em>m</em>.

Therefore, our slope is
.
1. Find the unit rate
15 books divided by 5 days = 3 books sold per day.
Since we are looking for how many days it would take the store to sell 21 bucks, we could do 21 (amount of books) divided by 3 (how much books is sold in a day).
Therefore, it will take a week / 7 days to sell 21 books.
I’m going to need a bit more information to offer help on this question. I’m sorry
