Find the slope of the line that passes through (1,2) and (2,4)
To find the slope of a line passing through two points, we use the formula:
slope = (change in y-coordinates)/(change in x-coordinates)
Given the points (1,2) and (2,4), the change in y-coordinates is 4-2 = 2 and the change in x-coordinates is 2-1 = 1.
Therefore, the slope is 2/1 = 2.
