Question
Identify a line having zero slope
- x = y
- x = 100
- y = 100
- x = 0
The correct answer is: y = 100
Hint:- Horizontal lines / lines parallel to x-axis have slope = 0.
Step-by-step solution:-
We know that when a line, plotted on a graph is represented by a Horizontal line, its slope is 0.
i.e. slopes of lines that are parallel to x-axis are 0.
Equations of lines that are parallel to x-axis are in the form y = b where b is the value of y-intercept.
Option C i.e. y = 100 is the only option that satisfies this condition.
Hence, y = 100 is the line having zero slope.
Final Answer:-
∴ Option C i.e. y = 100 is the correct answer.

George took a nonstop flight from Dallas to Los Angeles, a total flight distance of 1,233 miles. The plane flew at a speed of 460 miles per hour for the first 75 minutes of the flight and at a speed of 439 miles per hour for the remainder of the flight. To the nearest minute, for how many minutes did the plane fly at a speed of 439 miles per hour?
Note:
The relation between speed, distance and time given by the relation above is very important. There could be many such questions formed which ask us to calculate any of the three quantities with certain conditions involved.
