 Ch 3 Graphs   

The following questions deal with Ch 4.

Thinking hard and then answering them helps you going through the content. 

Pay attention when the right answers are explained!

Question about the previous slide:
Is this a good graph?

1. Yes, there are also graphs with negative coordinates.
2. No, this is just a funny fantasy.

explanation:

It also includes negative numbers.

Choose the correct meanings of the following words:
1. origin 2. a javelin 3. to plot

1. 1. oorsprong 2. speer 3. tekenen
2. 1. voorsprong 2. speer 3. samenzweren

More on coordinates

If an axis does not start at zero,
you should use a zigzag.

(the book often forgets to do this!)
