The slope of the line can be found by calculating the change in y-coordinates divided by the change in x-coordinates.
For the given points:
Coordinates -1,4 and 0,2:
Change in x-coordinates: 0 - (-1) = 1
Change in y-coordinates: 2 - 4 = -2
Coordinates 0,2 and 1,0:
Change in x-coordinates: 1 - 0 = 1
Change in y-coordinates: 0 - 2 = -2
Coordinates 1,0 and 2,-2:
Change in x-coordinates: 2 - 1 = 1
Change in y-coordinates: -2 - 0 = -2
Since the change in y-coordinates is consistently -2 for each change in x-coordinates, the slope of the graph is -2.
