What is the slope of the line that passes through the points (2, -1) and (2,0)?
To find the slope of a line passing through two points, we can use the formula:
slope = (change in y-coordinate) / (change in x-coordinate)
In this case, the two points are (2, -1) and (2, 0). The x-coordinate remains the same at 2, so the change in x-coordinate is 0. The y-coordinate changes from -1 to 0, so the change in y-coordinate is 1.
Therefore, the slope of the line is:
slope = (change in y-coordinate) / (change in x-coordinate) = 1 / 0 = undefined
The slope of the line passing through the points (2, -1) and (2, 0) is undefined.
