Question

What is the slope of the line ?

Answer 1

The slope is 0.

Why? The -6 keeps it in a straight line, going nowhere.

Answer 2

Slope of a line is equal to
`(y2-y1)/(x2-x1)`

In this case, its not necessary because as the x value increases (time),

the y value does not change. The slope is 0.

But, to use the slope of a line formula you would just take to points

y2 is a y value further along and y1 is a y value before. Same with x.
