**Answer:**

**Step-by-step explanation:**

Since we are given that the railing will begin at a height of 36 inches and follow the slant of the stairs, which decreases 9 vertical inches for every 12 horizontal inches.

**Thus the rate of change : **

**Rate of change represents the slope of line.**

Since we are given that height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs

**And the initial height of the railing was 36 inches .**

**So,the function which would represent the situation can be shown using equation of line : **

**y = mx+c**

So

c = 36 inches

So, the function :

**Hence The function which can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs :**

** **
