• prompt: jenny is graphing data she took about the amount of pages read over a certain number of weeks. she wants to put information from a table to a graph. explain how she would do this. in your response, answer the following questions.
• how many axes are on the coordinate plane and what should jenny label her axes?
• in the coordinate pair (4, 90). which number is the x-coordinate and which number is the y-coordinate?
• how do graphs help us with interpreting data?
• table:

number of weeks	1	2	3	4

Explanation:

1. Axes in Coordinate Plane: A coordinate plane has two axes: the x - axis (horizontal) and y - axis (vertical). For Jenny's data, the independent variable is the number of weeks, so she should label the x - axis as "Number of Weeks". The dependent variable is the number of pages read (since it depends on the number of weeks), so the y - axis should be labeled "Number of Pages Read".
2. Coordinate Pair (4, 90): In a coordinate pair \((x,y)\), the first number is the x - coordinate and the second is the y - coordinate. So in \((4,90)\), 4 is the x - coordinate (representing 4 weeks) and 90 is the y - coordinate (representing 90 pages read).
3. Graphing the Data: First, she identifies the ordered pairs from the table. For week 1 (x = 1) and 20 pages (y = 20), the pair is (1,20); week 2 (x = 2) and 50 pages (y = 50) gives (2,50); week 3 (x = 3) and 60 pages (y = 60) gives (3,60); week 4 (x = 4) and 90 pages (y = 90) gives (4,90). Then she plots these points on the coordinate plane (placing a dot at the intersection of the x - value and y - value for each pair). After plotting, she can connect the points (if appropriate, like in a line graph to show the trend) to form a graph.
4. Interpreting Data with Graphs: Graphs help in visualizing trends (like if the number of pages read is increasing, decreasing, or constant over weeks). For example, from Jenny's graph, we can see if the rate of pages read per week is changing (e.g., if the line is steep, more pages are read per week; if it's shallow, fewer). It also makes it easier to compare values (like how many more pages were read in week 4 than week 1) and to predict future values (extrapolating the trend to find pages read in week 5, for example). Text - to - world: In real - world, businesses use graphs to track sales over months (similar to pages over weeks) to make decisions. Text - to - self: Maybe a student can relate to tracking their own reading over weeks and using a graph to see their progress. Text - to - text: In math class, we learn about graphing linear and non - linear relationships, and this is an application of that knowledge.

Answer:

• A coordinate plane has 2 axes (x and y). Jenny labels x - axis "Number of Weeks" (independent variable) and y - axis "Number of Pages Read" (dependent variable).
• In \((4,90)\), 4 is the x - coordinate (weeks) and 90 is the y - coordinate (pages).
• Jenny plots ordered pairs from the table \((1,20)\), \((2,50)\), \((3,60)\), \((4,90)\) on the plane and connects points (if making a line graph) to show the trend of pages read over weeks.
• Graphs help visualize trends (e.g., increasing pages over weeks), compare values, and predict future data. They connect to real - world (business sales tracking), self (personal reading progress), and text (math graphing concepts).
