a. The graph has a positive slope, indicating that as time increases, the diameter of the fir tree also increases. The graph appears to be proportional, as the increase in diameter is relatively constant over time. The y-intercept of the graph is not explicitly given in the data.
b. The slope of the graph represents the rate at which the diameter of the fir tree is increasing per year. It shows that for every year that passes, the diameter of the tree increases by a certain amount.
c. Without the y-intercept explicitly given in the data, it is difficult to determine its meaning in context. However, if the y-intercept were to represent the diameter of the fir tree at time zero, it would indicate the initial size of the tree.
d. The graph of the line is showing the growth pattern of a fir tree over time. It demonstrates that as time progresses, the diameter of the tree increases.
(0,8), (10,15), (20,17), (30,23), (50, 31)
Y = diameter (in.)
X = time (yr)
graph name = Fir Tree Growth
a. Using the graph, describe the key characteristics of the graph (positive/negative slope, proportional/non proportional, y-intercept).
b. Write in words what the slope of the graph means in context.
c. Write in words what the y-intercept of the graph means in context.
d. Write in words what the graph of the line is showing.
