Put each value of x into the function$y=\frac{ 4 }{ 2-x }$and calculate the corresponding y-value. Can you do that for the first one?

4. Babynini

= -4.44444...

5. Babynini

so the first Q point is = (2.9, -4.44..)

Very good. So now you have the the coordinates of point Q on the secant line as (2.9, -4.444444). With point P given as (3, -4), can you calculate the slope of PQ?

7. Babynini

4.4444444

8. Babynini

Is that correct? :)

Recall that the slope calculation looks like$m_{PQ} = \frac{ y_Q - y_P }{ x_Q - x_p }$

Well done. That's correct. Now repeat these same calculations for each part of the question. Don't forget to keep six decimal places to satisfy the question.

Thank you so much!!

You're welcome.
