Which of the following equations best represents the regression line for the data given in the table above?
x y
1 4
2 1
3 5
4 10 a. y = 3x +2
5 16 b. y = 3x - 2
6 19 c. y = -3x + 2
7 15 d. y = -3x - 2

5x+2x=49

7x=49

x=7. 35 apples

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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.
