Question

For the graph y= 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your answer with two or more sentences

Answer 1

It is a horizontal line on 1

Answer 2

Parallel:
`m = 0` (Horizontal), Perpendicular:
`m = -(1)/(0)` (Vertical)

Explanation:

The equation y = 1 is an horizontal straight line (
`y = 0\cdot x + 1`). The slope of a line parallel to it is
`m = 0`. The slope of line perpendicular to it is
`m = -(1)/(0)`, since slope is represented by tangent function, which is undefined at
`\theta = \pm 0.5\pi`.
