"Slope "m = (y_2 - y_1) / (x_2 - x_1)

m = (1 - 7) / (9 - (-2))

#m = -6 / 11

Slope: -6/11

Explanation:

(-2, 7) and (9, 1)

Slope of a line is defined by "change in y"/"change in x" or "rise"/"run" or the formula (y_2-y_1)/(x_2-x_1).

We have the value of two points, so we can plug them into the formula:
(1-7)/(9-(-2))

Simplify...
(-6)/(11)

The slope is -6/11.

Hope this helps!
