Solve the equation 9= -8s -7

Here is how to work it out:

9= -8s - 7

9 + 7 = -8s - 7 + 7

16 = -8s

16/-8 = -8s/-8

s = -2

s = -2

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
