Slope is -
1/2 and (-5,6) is on the line.

What is y?

y int. = 8.5

Step-by-step explanation:

Use y=mx+b

6 = 1/2 (-5) + b

6 = -2.5 + b

6+2.5=-2.5+2.5+b

8.5=b

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.

the answer is a.

135 and 80
