Answer:
y=-11
Step-by-step explanation:
A line can be represented by a linear equation of

where m is the slope and y is the y intercept.
The slope is 0 so this function will be

Which is also called a constant function. The y intercept is -11. So the answer is

I think that the 2 or 4 one are right. This one is hard for me too but just hope that you get right and hope that it is right.
Answer:
y=-1x+1
Step-by-step explanation:
Ignore the triangle on the top. i am sure that the correct answer.
Answer:
A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.
Total distance covered by the man in terms of 'x' = (12.5x-285)miles
Step-by-step explanation:
Given:
Speed of a man = 'x' miles/hour
Time taken =
hour
So, distance = product of speed and time.
Distance covered in term of 'x' 
Now,
Speed =
miles/hour
Time taken=
hours
Distance
= 
= 
=
miles
Total distance covered by the man = Summation of
and 
= 
=
miles
So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.
