I think it’s C sorry if I’m wrong
Answer:
The slope of y = 1 is 0
explanation:
Determining slope has been based on a simple formula, y2-y1 over x2-x1.
It is crucial to follow this formula in order to attain the proper slope.
When a simple expression is given, for instance; y = 1 then it could be divided by 0; thus, resulting in the answer simply being zero.
However, x=1 would contain the slope of undefined because any number divided by zero results in an undefined answer.
This is pretty simple the first one is the second option the second one is the third option the third one is the third option and the fourth one is the first option
