The slope of the line can be calculated by using the formula:
slope = (change in y) / (change in x)
Using the points (0,0) and (2,-2), we can calculate the slope as follows:
slope = (-2 - 0) / (2 - 0)
slope = -2 / 2
slope = -1
Therefore, the slope of the line passing through the given points is -1.
The correct answers are:
-1
negative 1
