Final answer:
To determine the slope of a linear function, you need to find the rise and run, which are the vertical and horizontal changes between two points on the graph.
Step-by-step explanation:
The slope of a linear function can be determined from the graph by finding the rise and run. The rise is the vertical change between two points on the graph, and the run is the horizontal change between the same points. The slope is then calculated by dividing the rise by the run.
In this case, since the graph of the linear function is not provided, we cannot directly determine the slope. Therefore, we need more information to calculate the slope.
For the second question, we can use the given points (1, 0.1) and (7, 26.8) to find the slope. The rise is 26.8 - 0.1 = 26.7, and the run is 7 - 1 = 6. The slope is then 26.7 / 6 = 4.45.
