Question

How do you find the x and y intercepts of `y=-2`?

Answer 1

There is no `x`-intercept.

The `y`-intercept is `(0,-2)`

Explanation:

The line `y=-2` is a horizontal line.
It passes through the `y`-axis at `(0,-2)`

The value of `y` stays the same, regardless of which `x`-value is used.

There is no `x`- intercept, because:

• the line is horizontal
• on the `x`-axis, `y=0`, this is not possible because `y=-2`

Answer 2

There is no x intercept if the line is y only

Explanation:

There is a straight, horizontal line going across the graph at y=-2. Therefore, the y intercept is -2
