From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:

Substitute these points in the formula.

Hence, the distance is √5
Answer
The correct answer is the letter A because a division problem shows a total amount being broken into equal parts.
Choice a talks about how many parts it would take to get the total of 212 m of ribbon.
This choice includes the parts and total information.
Original Price = Final Price / (100 - Discount)
So...
OP = 360 / 100 - 0.40
OP = 360 / 0.60
OP = 600
The original price is $600.
To check, do 600 - (600 * 0.40) in a calculator. You get 600 - 240 = 360, the discounted cost.
I believe it’s 80 hope it helps
