Question

How do you calculate the slope of (-1.-1) and (4,-6)?

Answer 1

Use the standard formula for slope to find `m = -1`.

Explanation:

The slope `m` of a line passing through points `(x_1, y_1)` and `(x_2, y_2)` is given by the formula:

`m = (Delta y)/(Delta x) = (y_2 - y_1) / (x_2 - x_1)`

Let `(x_1, y_1) = (-1, -1)` and `(x_2, y_2) = (4, -6)`

Then

`m = (y_2 - y_1) / (x_2 - x_1) = (-6 - (-1)) / (4 - (-1)) = -5 / 5 = -1`
