I need some help, pls

5/2

Step-by-step explanation:

Rise = 5

Run    2

Now, with that,  our y intercept is -6 because the line hits the y axis at -6 units. Then, we can setup our own equation for y=

and that is y=5/2 x -6

Then I have attached a graph below to certify my answer.

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.
