Understanding Graph Intercepts and Ordered Pairs

The video tutorial explains how to analyze a graph showing Sally's distance from home over 22 minutes. It covers the interpretation of vertical and horizontal intercepts and the significance of ordered pairs. The vertical intercept indicates Sally starts 11 miles from home, while the horizontal intercept shows she arrives home after 22 minutes. The ordered pair (6, 8) signifies that after 6 minutes, Sally is 8 miles from home.

What does the graph represent in the context of Sally's journey?

• Sally's travel expenses

• Sally's distance from home over time

• Sally's speed over time

• Sally's favorite places

In an ordered pair, what does the first value typically represent?

• The output

• The distance

• The speed

• The input

How is the input value represented on a graph?

• As a curve

• Along the vertical axis

• Along the horizontal axis

• As a diagonal line

What does the output value in an ordered pair represent in this context?

• Distance from home in miles

• Sally's speed

• Time in minutes

• Sally's direction

What is the significance of the vertical intercept in the graph?

• It represents Sally's speed

• It indicates Sally's initial distance from home

• It shows the time Sally starts her journey

• It marks the end of Sally's journey

What is the ordered pair for the vertical intercept in this graph?

• (22, 0)

• (11, 0)

• (0, 11)

• (0, 22)

What does the horizontal intercept tell us about Sally's journey?

• The distance Sally travels

• Sally's favorite route

• The time Sally reaches home

• Sally's maximum speed

What is the ordered pair for the horizontal intercept in this graph?

• (22, 0)

• (11, 0)

• (0, 11)

• (0, 22)

What does the ordered pair (6, 8) indicate in the graph?

• Sally is 6 miles from home after 8 minutes

• Sally is 8 miles from home after 6 minutes

• Sally travels 6 miles in 8 minutes

• Sally travels 8 miles in 6 minutes

What does the time value in the ordered pair (6, 8) represent?

• The time elapsed since Sally started

• The time Sally starts her journey

• The time Sally takes a break

• The time Sally reaches home
