Answer 2

First you want to look at what the two points have in common, that would tell you what the line is doing or where it is located.

Do you see how both points share a y coordinate of 4? That means that both points are on the horizontal line made at y=4 and do not move from that point. That makes this a horizontal line through y=4. The part where the line moves is between the x numbers, or location on the x axis. Those numbers will be what you use to determine how far apart the points are.

So, what do you think the answer is, or what do you think you should do here?

Answer 4

Which steps could be used to solve this story problem?



The librarian was organizing some books on some shelves. She had 200 fiction books, 100 non-fiction books, and 38 magazines. She decided to put all of the magazines in a box. She put an equal number of books on each of 6 shelves.



How many books should the librarian put on each shelf?









A.
Add together 200 and 100. Then divide the sum by 6.







B.
Subtract 100 from 200. Then add 6 to that difference.







C.
Multiply 200 × 6. Then subtract 100 from that product.







D.

Divide 200 ÷ 100. Then add 6 to that quotient.
