The gradient (slope) of the curve at the midpoint at which the changes are calculated or the derivative of the curve at that point. These are only crude approximations unless the function is linear or if the changes are taken over very very small intervals. Equivalently, it is the slope of the tangent to the curve.

rise over run or change in y over change in x

To find the rate of change on a table: the input is X and the output is Y (the left side is X and the right is Y). The formula for the rate of change is: Change of the dependent variable over change of independent variable or y over x. ^^^ I understood NONE of that...

Yes, that is correct.

The change in y over the change in x

You change the value of y to -y. ex: (4,5) reflected over the x-axis is (4,-5)

For a reflection over the x axis, leave the x coordinate unchanged and change the sign of the y coordinate.For a reflection over the y axis, leave the y coordinate unchanged and change the sign of the x coordinate.
