Question

How do you find the slope of a line A(-10,0) B(0,-10)?

Answer 1

slope = (change in `y`) / (change in `x`)

That is: given two points `(x_0, y_0)` and `(x_1, y_1)` through which a line passes, the slope `m` is given by the formula:

`m = (Delta y)/(Delta x) = (y_1 - y_0) / (x_1 - x_0)`

In your case:

`m = (-10 - 0) / (0 - (-10)) = (-10)/10 = -1`
