Answer:

Step-by-step explanation:
Let the equation be : 
The point (1,1) must satisfy this equation.

Similarly, the point (1,3) must satisfy:

Also for the point (9,2), we have:

Solving the equations (1), (2) and (3) simultaneously, we get:

We Substitute this values to get:


Multiply through by 8 to get:

Answer:
(-8) + (-8) + (-8) + (-8)
Step-by-step explanation:
Since Yan is descending ; we represent his movement as being negative.
Number of rungs descended before stopping = 4
Number of stops = 8
Given that no extra steps was taken ;
Number of ladder rungs descended :
4 rungs per stop for 8 stops
- 4 * 8 = - 32 rungs
Another way to write the product :
Number of stops added in number of rungs descended :
(-8) + (-8) + (-8) + (-8)
Answer:
yes
