Question

What type of line is the graph of `y=7`?

Answer 1

Horizontal.

Explanation:

Because there is no "`x`" component, the slope is zero.

(The equation can be written as `y=0x+7`).

Thus, `y` will always be `7`, creating a horizontal line.

Answer 2

Horizontal line with a `y`-intercept at `7`

Explanation:

The equation of the line can be written as `y =0x +7`

This is in the form `y = mx+c` and we can see that the slope is 0.

The line only has a `y`-intercept of 7.

The graph is therefore a horizontal line passes through
the point `(0,7)`
