Given:
Points (-9, -6) and (3,-9)
x1 =-9
x2 =3
y1 = -6
y2 =-9
Solve for the slope of the line.
Slope of the line formula:
m = change in y over change in x
or
m =delta y / delta x
Solution:
Substitute the given values of x1 ,x2 ,y1 and y2 to the given equation for the slope of the line.
m = (-9-(-6)) /(3-(-9))22u.l
m = -3/12
m = - ¼
The slope of the line through (−9,−6) (3,−9) is ¼.
