Points that mean something.The big ideaA point is a fact. Across is one thing and up is another. Read the numbers on the axes.
How it works
A point is a fact. Across is one thing and up is another.
Read the numbers on the axes to see what a point means.
Point A at 10 across and 45 up on a savings graph means after 10 weeks there are 45 dollars.
Example 1: Read a point
- Ana measures her plant every week. A point is at 6 across and 10 up.
- Across is the weeks, up is the height.
- After 6 weeks the plant is 10 cm tall.
Example 2: Say what it means
- Ben's point A is at 10 across and 45 up.
- Across is weeks and up is dollars.
- After 10 weeks, Ben has saved 45 dollars.
Example 3: Plot a fact
- After 18 minutes Cleo has walked 20 blocks.
- Go across 18 minutes, then up 20 blocks.
- Mark that point.
