Answer:
The equation of the horizontal line passing through (4, 9) will be:

Please also check the attached line graph.
Step-by-step explanation:
We know that the equation of a horizontal line is always the kind of equation such as:

- As in the pint (4, 9), ordinate is 9.
- In other words, y=9
Thus, the equation of the horizontal line passing through (4, 9) will be:

Answer:
D
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = - 3 , then
= 8 - 3(n - 1) = 8 - 3n + 3 = - 3n + 11 → D
Answer: 
Step-by-step explanation:
Given
The yellow line leaves the station every 6 min
The red line leaves the station every 8 min
They both leave at 
Both trains meet again after, LCM(6,8)=24 min
i.e. at
