Question

How do you determine the slope of the line passing through (5,-6) and (3,-6)?

Answer 1

The slope is zero. The line is the line
`y = -6`

Explanation:

Slope:

`m = (y_2 - y_1)/(x_2 - x_1)`

Where,

• `y_2 = -6`, `y_1 =-6`
• `x_2 = 3`, `x_1 = 5`

The result is `0`.

Because both `y` values are `-6`, the line must pass through this value, and zero slope means it is parallel to the `x`-axis.
