12. The graph of a linear function f passes through the points (4, w) and (r, 7) in the xy - plane and has a slope of
Which of the following is true?

A) r + w= 4/5
B)4r - 5w = 19
C) -9rw = 51
D) 4r + 5w = 51

no

Step-by-step explanation:

1 number

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.
