Which stock price had the largest change? How do you know? What is the distance between (a, 5) and (a, -3)? Students continue tracking their investments and work on strategies for calculating length of horizontal and vertical lines.
Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. For example, interpret –3 > –7 as a statement that –3 is located to the right of –7 on a number line oriented from left to right. (Combine and relabel)
Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in a real-world situation. For example, for an account balance of –30 dollars, write |–30| = 30 to describe the size of the debt in dollars.
