Question

Is the line for the equation y = 1 horizontal or vertical? What is the slope of this line? Select the best answer. (2 points) a The line is horizontal. The slope is 0. b The line is horizontal. The slope is 1. c The line is vertical. The slope is undefined. d The line is vertical. The slope is 0.

Answer 1

The answer is the option A

The line is horizontal. The slope is

Explanation:

we know that

The slope of the line parallel to the x-axis is equal to zero and is called a horizontal line

The slope of the line parallel to the y-axis is undefined and is called a vertical line

In this problem we have

This is a line parallel to the x-axis

therefore

Is a horizontal line with slope equal to zero
