Solution
Find the y-intercept for following equation:

Using the slope equation formular:

The value of y when x = 0

Hence the answer is - 1
Answer:
a. 
Step-by-step explanation:
Given that

Now
if one is added i.e.

Now let us assume the other polynomial be x
So,


The total area of the stable is 20,250 sq. ft.
Let n = total number of box stalls.
Each box stall is a square of length 9 ft.
Total area = 9^2n = 81n ft².
Therefore
81n = 20250
n = 20250/81 = 250
Answer: 250 horses.
