Question
Identify a line with an undefined slope.
- y = x
- y+ x =0
- y = 10
- x = 1
The correct answer is: y = 10
Hint:- Verticle lines / lines parallel to y-axis have undefined slope.
Step-by-step solution:-
We know that when a line, plotted on a graph is represented by a verticle line, its slope is undefined.
i.e. slopes of lines that are parallel to y-axis are undefined.
Equations of lines that are parallel to y-axis are in the form x = a where a is the value of x-intercept.
From the given options, option d is the only option with equation of line in this format i.e. x = a i.e. x = 1.
∴ option d is the correct option.
Final Answer:-
∴ Option d i.e. x = 1 is the correct option.

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.
