I need help with slopes and lines.

Determine the slope of each line

a line through points (-1, 2) and (2, -7)

Slope of a line through two points (x1, y1) and (x2, y2) is (y2 - y1)/(x2 - x1).

So substituting the given points we have (-7 - 2)/(2 - (-1)) i.e -9/3 = 3

Oops. it should be -3

g is correct.
