The transformation from y = f(x) to y = f(x - 4) - 2
Yes. The transformation from y = f(x) to y=f(2x) will compress the shape along the x-axis by a factor of 2.
Change in y values over change in x values. Rise over run.
change in y values of 1st and last points divided by the change in x values of the 1st and last points
In math, the slope of a line represents its steepness. It is the change in y values over the change in the values of x, or rise over run.
