Using the rise/run counting method, the slope of the line is

the slope of the line is -2/3

Step-by-step explanation:

In the rise/run counting method:

first, you have to select two points of the graph - (0, 1) and (3, -1) in this case.then, you have to count the "rise", that is, the difference between the y-coordinates of the points - in this case: -1 - 1 = -2the next step is to count the "run", that is, the difference between the x-coordinates of the points - in this case: 3 - 0 = 3finally, you can compute the slope as rise/run - in this case, slope = -2/3
