Because that's the definition of 'slope'.
Slope equals rise over run.
RUNRun.
The slope can be remembered as "rise over run". When the slope is an integer, it means that the rise over run is positive.
Slope is 'rise over run', that is rise divided by run. In this case, that's 12 divided by 6, which equals 2.
If you're talking about slope, it is rise over run. But why is it not the other way run over rise?
Answer: run.
run over rise
rise over run
Rise over run
slope of line is the ration of the rise over the run
The slope of a straight line can't be measured in units. If it is a horizontal line then there is no slope because the rise over run is 0/x, which equals zero because zero divided by everything is zero. If the line is vertical then the slope is undefined because the rise over run is x/o.
Well I think that slope is rise over run or y over x.So if y= -6+3 or -3 than the slope should be -3/x
