Estimate the slope of the line from the graph.

Question

Quizplus · Accepted Answer

The slope is determined by the change in y (vertical change) divided by the change in x (horizontal change). From the graph, we can see that for every 2 units to the right (change in x), the line increases by 12 units (change in y). Therefore, the slope is 12/2 = 6. The slope can be estimated by choosing two points on the line and finding the rise/run between them. From the graph, we can see that the line passes through the points (1,7) and (4,25). The rise between these points is 18 (25-7) and the run is 3 (4-1), giving a slope of 6 (18/3). Therefore, the best choice is E.
