Line A has a slope of 4. Line B has a slope of 1/4.
Line A has a slope of 4. Line B has a slope of 1/4.
The correct answer is actually (a) because rate of change is x/y (or that's how I learned it) then the more big the slope the bigger the rate of change
Line A is correct because the rule is rise over run and since the rise is 4 and run 1, the answer is 4.
