C) m = 2

Quizplus · Accepted Answer

The slope of a line is given by the formula: slope = (change in y) / (change in x). From the graph, it can be observed that the line moves up 6 units (change in y) and moves to the right 3 units (change in x) from the first point to the second point. Therefore, slope = 6/3 = 2. The only option that matches this is option B, so that is the answer. The slope of a line is calculated by the ratio of the vertical change (rise) to the horizontal change (run) between two points. From the two points indicated on the graph, there is a rise of 8 units and a run of 4 units. Therefore, the slope of the line is 8/4 = 2. Choice B is the only option that has a slope of 2.
