Which of the following best describes the slope of the line below
2 answers:
Answer: The correct option is C, i.e., Negative slope.
Explanation:
Reason for correct option:
From the given graph it is noticed that the as the value of x increases the value of y is decreased. This inverse relationship between the values of x and y shows that the line have negative slope and the correct option is C.
Reason for incorrect option:
If the relationship between x and y is positive (y increase as x increase and vice versa), then the slope is positive. So, the option A is incorrect.
If the value of y changes without any change in the value of x , then it is an undefined slope. It is represented by a horizontal line. So the option B is incorrect.
If the value of x changes but the value of y remains constant, then the slope of line is zero, it is defined by a vertical line. So, the option D is incorrect.
If slope is represented by m, then the line having different slopes are shown in below figure.
