Flashcard 1: Identify the pattern: weight changes from 7 to 7 to 7. What is the total change in weight?
Answer: Total change is 0. 7−7=0 for each step and overall.
Flashcard 2: Which change in weight between consecutive points indicates constant weight: 0 or +2?
Answer: 0. No change means difference of 0 between points.
Flashcard 3: Identify the pattern on a bar graph: bars at 6,6,6 units. What happens to weight?
Answer: Weight stays the same at 6 units. All bars at height 6 show no variation.
Flashcard 4: Identify the constant segment: a line graph goes from (0,5) to (2,5) to (4,9). When is weight constant?
Answer: From x=0 to x=2. Both points at y=5 form a horizontal segment.
Flashcard 5: Identify the constant segment: points are (1,10), (3,10), (5,10). Over what interval is weight constant?
Answer: From x=1 to x=5. All three points have y=10, spanning this interval.
Flashcard 6: What does it mean if a weight graph is flat even though time increases?
Answer: Time changes, but weight does not change. Flat means weight stays constant as time progresses.
Flashcard 7: Identify the pattern: a line graph has points at (1,5), (2,5), (3,5). What happens to weight?
Answer: Weight stays the same at 5 units. All y-coordinates equal 5, showing no change.
Flashcard 8: Identify the pattern: a line graph has points at (0,8) and (4,8). What happens to weight?
Answer: Weight stays the same at 8 units. Both points have the same y-value of 8.
Flashcard 9: Which graph best shows constant weight: a flat line at y=9 or a line from (0,2) to (4,10)?
Answer: A flat line at y=9. The sloped line shows weight increasing from 2 to 10.
Flashcard 10: Identify the constant weight: (1,3), (2,4), (3,5). Does weight remain the same?
Answer: No; weight increases. y-values go from 3 to 4 to 5, showing increase.
Flashcard 11: Identify the pattern: weights are 4,4,4,4 at times 1,2,3,4. What does the graph show?
Answer: A horizontal line; weight is constant. All weights equal 4, creating a flat line.
Flashcard 12: What is the best description of a constant-weight trend on a bar graph?
Answer: All bars are the same height. Equal heights mean equal values across categories.
Flashcard 13: What does the term constant weight mean when reading a graph?
Answer: The weight value does not change across the graph. Constant means unchanging or staying at the same value.
Flashcard 14: What does a horizontal line on a weight-versus-time line graph indicate?
Answer: Weight remains the same (constant) over time. A horizontal line has zero slope, indicating no change.
Flashcard 15: Which graph pattern shows weight stays the same: horizontal, rising, or falling line?
Answer: Horizontal line. Only horizontal lines show no change in y-values.
Flashcard 16: Which statement matches a constant-weight graph: “y stays the same” or “y increases as x increases”?
Answer: y stays the same. Constant weight means y doesn't vary with x.
Flashcard 17: Which graph feature best shows weight stays the same: horizontal, rising, or falling line?
Answer: A horizontal line. Horizontal lines show no change in y-value (weight) over time.
Flashcard 18: What is the slope of a weight graph line when weight remains the same?
Answer: Slope is 0. No vertical change means rise over run equals zero.
Flashcard 19: Identify the pattern in a table when weight stays the same across different times.
Answer: The weight values repeat (all equal). Constant weight means the same value appears in every row.
Flashcard 20: Which statement matches a constant-weight graph: "y changes" or "y stays the same"?
Answer: "y stays the same.". Constant weight means the y-value doesn't change.
Flashcard 21: What does it mean if all plotted points have the same y-value on a weight graph?
Answer: Weight is the same for all measurements. Points at the same height show no weight variation.
Flashcard 22: Identify the constant weight shown by points (0,12),(4,12),(9,12) on a graph.
Answer: 12 (units of weight). All three points share the same y-value.
Flashcard 23: Which option shows constant weight: points (1,5),(2,5),(3,5) or (1,5),(2,6),(3,7)?
Answer: (1,5),(2,5),(3,5). All points have the same y-coordinate of 5.
Flashcard 24: Identify whether weight changes if a weight-vs-time line is flat from t=0 to t=10.
Answer: Weight does not change. A flat line shows zero change in weight.
Flashcard 25: What is the y-intercept on a constant-weight graph if the weight is always 8N?
Answer: 8N. The y-intercept equals the constant weight value.
Flashcard 26: What is the average rate of change if weight is 20N at both t=1 and t=6?
Answer: 0N per time unit. No change divided by time interval equals zero.
Flashcard 27: Identify the correct conclusion if a weight graph has slope 0 between t=3 and t=9.
Answer: Weight is constant from t=3 to t=9. Zero slope indicates no change in weight.
Flashcard 28: Which line segment shows weight stays the same: from (2,6) to (8,6) or from (2,6) to (8,10)?
Answer: From (2,6) to (8,6). Both points have the same y-coordinate, showing no change.
Flashcard 29: What is the change in weight from t=2 to t=7 if the graph is horizontal at 15N?
Answer: 0N. Horizontal lines show no weight difference between any two points.
Flashcard 30: Identify the constant weight if a line is horizontal at y=9 on a weight graph.
Answer: 9 (units of weight). The horizontal line's y-value is the constant weight.
