Question

How do you find the slope of (–9, –1) and (–2, –1)?

Answer 1

Slope: `m=0`

Explanation:

Slope is defined as the change in `y` divided by a corresponding change in `x`.

Given two points `(x_1,y_1)` and `(x_2,y_2)`
the change is `y` is `Delta y = (y_2-y_1)`
and the corresponding change in `x` is `Delta x = (x_2-x_1)`

For the specific points `(-9,-1)` and `(-2,-1)`
we can see that the slope `m` is
`color(white)("XXX")(Delta y)/(Delta x) = ((-1)-(-1))/((-2)-(-9)) =0/7=0`
