what is the slope of a line through the points (4,8)and(1,6)

Question

Useing the slope formula.

Answer 1

deltay...from 8 tu 6=-2

deltax...from 4 tu 1=-3

slope=-2/-3=2/3=0.66666

Answer 2

The slope of the line is:  m= (Ysub2 - Ysub1) / (Xsub2 - Xsub1), where m is the slope of the line and Xsub1 is not equal to Xsub2.

Solution:  Let the first ordered pair (4, 8) be called (Xsub1, Ysub1) and the second ordered pair (1, 6) be called (Xsub2, Ysub2).

Substituting the values for m = (Ysub2 -Ysub1) / (Xsub2 - Xsub1)  we have 

m = (6-8) / (1-4)

m = -2 / -3

m = 2/3  Therefore the slope of the line is 2/3.

Answer 3

points (4,8) & (1,6)

deltax=4-1=3

deltay=8-6=2

slope=deltay/deltax=2/3
