Question

what does the slope mean?

Answer 1

The change in y over the change in x, or the rise of a line over the run or if you are talking about a real life example, the rate of change. For example, if I buy tshirts at 5 dollars each my rate is 5 per shirt or 5/1 the rise is 5 and the run is 1.

Answer 2

In your chart the slope is not going up or down if you look at the dotted line. So the rate is not changing. So if y is 84 at one point and still 84 at another point, the slope is 84-84 / change in x .

Answer 3

if you look closely at the line it is slightly downward.

Answer 4

slope tells us an approximation of the limit, or as we take x-values that go to infinity, the value the behavior of the function will approach. It is the rate of change of a function.

In this case, as we keep calculating the pitch speed/# of pitches, we see that it estimates to about 82, or whatever that line is.
