Find the slope of the line that contains the points named.<br><br> X(2, -1), Y(0, 4)
fgiga [73]

Answer:

- 4/3 0r - 1 1/3 0r - 1.33333333 ( the 3 keeps repeating)

Step-by-step explanation:

I would suggest to use a table so....

x         y

2        0

-1         4

from 0 to 4 you add 4

from 2 to -1 you subtract 3

so y/x

4/-3 = - 1 1/3 or - 1.333333

Hope this helped a little!
