A price chart is a line of prices over time, and it shows the past only.
A price chart has two lines: across is time (here eight weeks) and up is the price. A dot shows one moment.
Joining the dots with a line shows how the price moved. A climbing line is a rising price, and a falling line is a falling price.
A steeper line means a bigger change in one week. A price chart shows the past only: it does not show next week.
These are some of the questions on the sets. The printable sheets have more and an answer key.
