Question

What is the slope of the line y = 3? (1 point)

Undefined

0

−3

3

Answer 1

B: 0

Since the y-intercept of the line is 3, it will be a horizontal line. It neither indicates the slope is going up or down, instead it's perfectly straight. It would not be undefined, because the y value is a follows the rules. It can't be -3 or 3, because it gives no indication of the x value. So, the answer is 0.

Answer 2

The line y = 3 is a perfectly straight, horizontal line crossing at, well, y = 3.

The slope (or the gradient) of a line, is by how much the line is ascending or descending, essentially.

y = 3, being a perfectly horizontal line, does not ascend or descend, thus making its slope ZERO (0).
