The question is incomplete.
Since we are not given the rise and run of the slope. We can as well use the following values;
rise = 8
run = 4
Slope of the line is expressed as;
Slope = rise/run
Substitute the given values in the formula;
slope = 8/4
slope = 2
Hence the slope of the line is 2.
NB: The values of rise and run are assumed values. Kindly use the same method for any values of run and rise.
