 | What is the formula for the slope of a line in a line graph, given two points (x₁, y₁) and (x₂, y₂)? |  Card: 1 / 20 |
| The slope of the line is calculated as (y₂ - y₁) / (x₂ - x₁). | Card: 2 / 20 |
| If a line graph shows a constant increase of 3 units per time interval over 5 intervals, what is the total increase in the dependent variable? | Card: 3 / 20 |
| The total increase is 3 units × 5 intervals = 15 units. | Card: 4 / 20 |
| Fill in the blank: The independent variable is plotted on the ___ axis of a line graph. | Card: 5 / 20 |
| X | Card: 6 / 20 |
| True or False: The Y-axis represents the independent variable in a line graph. | Card: 7 / 20 |
| False. The Y-axis represents the dependent variable. | Card: 8 / 20 |
| If a line graph shows a decrease of 2 units each time for 4 consecutive time intervals, what is the overall change? | Card: 9 / 20 |
| The overall change is -2 units × 4 intervals = -8 units. | Card: 10 / 20 |

| What is the significance of using consistent scaling in line graphs? | Card: 11 / 20 |
| Consistent scaling allows for accurate comparison of data across multiple graphs. | Card: 12 / 20 |
| Riddle: I connect points to show changes over time, what am I? | Card: 13 / 20 |
| A line graph. | Card: 14 / 20 |
| If the data points on the Y-axis are 4, 8, 12, and 16, what is the average of these points? | Card: 15 / 20 |
| The average is (4 + 8 + 12 + 16) / 4 = 10. | Card: 16 / 20 |
| Fill in the blank: To create a line graph, one must first collect ___ that needs representation. | Card: 17 / 20 |
| Data | Card: 18 / 20 |
| True or False: Multiple lines on a line graph can represent different datasets for comparative analysis. | Card: 19 / 20 |
| True. | Card: 20 / 20 |
