What type of slope does a horizontal line have? A) Positive
B) Zero
C) Undefined
D) Negative

0Slope of a horizontal line. When two points have the same y-value, it means they lie on a horizontal line. The slope of such a line is 0, and you will also find this by using the slope formula.The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).THE ANSWER IS ZEROPLEASE SUBSCRIB E TO MY CHANNEL LOOK AT THE IMAGE
