Question

what is the slope between the two points (-1, -1) and (8, 0)?

Answer 1

Have you see the equation:
\[\huge m={y_2 - y_1 \over x_2-x_1}\]

Answer 2

Where m is the slope, IE:
\[\huge y=mx+b\]

Answer 3

This here is the slope formula. Just plug in the coordinates.
\[m = \frac{y_{1} - y_2}{x_1 - x_2}\]\[m = \frac{y_1 - y_2}{x_1 - x_2} \implies \frac{-1 - 0}{-1 - 8} \implies ?\]

Answer 4

and so the answer would be 1/9 !

Answer 5

Yup :)

Answer 6

Thanks!
