• Reading from left to right

• Reading from bottom to top

• Reading from top to bottom

Which term is NOT associated with an increasing trend in a graph?

• Gained

• Ascending

• Fell

What does a constant trend in a graph indicate?

In a graph showing temperature over time, what does a horizontal line represent?

• Temperature is increasing

• Temperature remains constant

What does a continuous graph allow that a discrete graph does not?

• Specific amounts only

• Fractions and decimals

• Only whole numbers

• No connection between points

Which of the following is an example of a continuous variable?

• Number of shoppers

• Height of a plant

• Number of animals

• Number of books

Why do we not connect points in a discrete graph?

• Because the values can be fractions

• Because the values are specific amounts

• Because the values are decimals

• Because the values are continuous

Which of the following scenarios would be represented by a discrete graph?

• Distance traveled over time

• Height of a plant over time

• Number of shoppers each day

• Temperature changes over time

In the context of graph interpretation, what does 'discrete' mean?

• The situation can include fractions or decimals

• The situation must have specific amounts

• The points are connected

• The values are continuous
