The slope of line p will be -3
'The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.'
According to the given problem,
The slope of the line q is -3.
Now, for the lines to be parallel to each other, the slope has to be the same. If the slope is different for the two lines, then the lines will not be parallel. They will be intersecting or diverting lines.
Therefore, the slope of line p is -3.
Hence, we can conclude, the slope of the line p is -3.
