The point P(8, −3) lies on the curve y = 3/(7 − x). (a) If Q is the point (x, 3/(7 − x)), use your calculator to find the slope mPQ of the secant line PQ (correct to six decimal places) for the following values of x. (i) 7.9 mPQ =

Slope of the line

Step-by-step explanation:

Given that,

The point lies on the curve .

If is the point lies on .

To find:- Find the slope of line .

So,  

The coordinates of point when it lies on

        if then

       So,   ≡ and many points can be calculated by given Equation.

Using the formula when two points .

Then, substituting the coordinates we get,

                ⇒  

Therefore,

Slope of the line

its 69.420
