Question

How do you find the slope of a line parallel to the graph of each equation y=6?

Answer 1

`m = 0`

Explanation:

Parallel lines have the same slope.
The line parallel to `y = 6` will have the same slope as the given equation.

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

For the given equation, `y = 6`, any value of `x` would yield the same value for `y` (which is 6).

Hence we have

`m = (6 - 6)/(1 - 2)`

`=> m = 0/-1 = 0`
