Final answer:
The 'm' in the equation represents the slope of a line on a graph and can be calculated using the formula slope (m) = change in y / change in x.
Step-by-step explanation:
The 'm' in the equation represents the slope of a line on a graph. The slope indicates how much the line moves up or down on the y-axis. It can be calculated using the equation:
slope (m) = change in y / change in x
For example, if the line moves 2 units up for every 3 units to the right, the slope would be 2/3. You can find the slope by calculating the ratio of the vertical change to the horizontal change.
