Final Answer:
The given statements are true, a) The graph represents a straight line going up and to the right.
b) When time is 0, height above sea level is 0.
Therefore, correct options are a) True, b) True
Step-by-step explanation:
(a) The statement "The graph represents a straight line going up and to the right" is true because the graph depicts a linear relationship between time and height, showing a consistent positive slope.
(b) The statement "When time is 0, height above sea level is 0" is true as the graph intersects the y-axis at 0, indicating that at time 0, the height above sea level is indeed 0.
(c) The statement "When time is 4 seconds, height above sea level is -12 ft" is false. The graph does not intersect the y-axis at -12 when time is 4 seconds, indicating an error in interpreting the graph.
(d) The statement "The graph represents a parabolic curve" is false. The graph shows a linear relationship, not a curved one.
Understanding how to interpret graphs is crucial in various fields, as it allows for accurate analysis and predictions based on visual representations of data. In this case, recognizing the characteristics of a linear graph aids in understanding the relationship between time and height above sea level.
Therefore, correct options are a) True, b) True
