How can slope be represented?
change in y/ change in x, rise over run
What does rise represent and what does run represent?
Rise represents the change in y-values on a graph, e.g. if the rise is equal to 10, the y-value changes by 10. Run represents the change in x-values on a graph, e.g. if the run is equal to 5, the x-value changes by 5. knowing both the rise and the run is necessary to calculate the gradient, or slope of a graph - this is done by dividing the rise by the run, in this case it would be equal to 10/5 = 2
The run is the change between two points on a line?
Run is the two x coordinates when finding the slope (change) of a line. They go on the bottom (rise over run)
What does rise or run mean?
rise refers to the y coordinates(i.e y2 - y1) whereas the "run" refers to the x coordinates(i.e x2 - x1), hence the algebraic expression slope = rise/run or to put it mathematically, m = (y2 - y1)/(x2 - x1) or m = change in y/change in x.
The slope of a line is the ratio of what?
Rise/run or y-value change (can be negative) / x-value change (can be negative)
