5. Which of the following is always true about the graph of a horizontal line?
A. The graph will have a positive y-intercept.
B. The graph will have a negative y-intercept.
C. The slope of the graph will be undefined.
D. The slope of the graph will be zero.

D. The slope of the graph will be zero.

Step-by-step explanation:

Slope of a line is given as .

For a horizontal line, the rise is always equal to zero since the line doesn't rise vertically. This means, .

No matter the value of the run, , when we divide zero by the value of the run, we would always have 0.

Therefore, the slope of an horizontal line would always be zero.
