On a graph, what would be the slope of

(0,-2); (0,1)?

To find the slope of a line on a graph, you can use the formula:

Slope (m) = (y2 - y1) / (x2 - x1)

Given the points (0, -2) and (0, 1), you can substitute the coordinates into the formula:

Slope (m) = (1 - (-2)) / (0 - 0)

Simplifying this expression, we get:

Slope (m) = (1 + 2) / 0

However, a division by zero is undefined. In this case, the denominator is zero, which means that the slope does not exist. This indicates that the line represented by the given points is vertical.
