It is clear from the accompanying graph that the value of y decreases as the value of x grows. The line has a negative slope, and the right answer is C, as shown by the inverse connection between the values of x and y.
Reasoning for other incorrect options:
The slope is positive if the connection between x and y is positive (y rises as x rises, and vice versa). As a result, choice A is incorrect.
It is an undefined slope if the value of y varies without the value of x changing. A horizontal line is used to symbolize it. Option B is thus untrue.
The slope of a line is zero and is determined by a vertical line if the value of x varies but the value of y stays the same. So, the option D is incorrect.
If slope is denoted by m, then the line with various slopes is depicted in the picture below.
