Answer:
The change will be that of run over run.
Explanation:
In the equation, y= -3x - 2 it moves 3 spaces down directly on the y-axis and 1 space to the right from there in the direction of the x-axis. Although, if you were to change the slope from -3 to -1/3 it will move 1 space down directly on the y-axis and 3 spaces to the right from there in the direction of the x-axis.
Image in green is the equation of: y= -3x - 2
Image in red is the equation of: y= -1/3x - 2
