First let's convert the decimal numbers to mixed numbers:

Now, adding all the numbers, we have:

So the correct option is B.
The formula to find slope it (y2-y1)/(x2-x1)
(2,4) is the first point
(6,2) is the second point
(2-4)/(6-2)
-2/4 which can be simplified to -1/2
Hope this helps
This is linear. 8x-5y=15
-5y=15-8x
Divide -5
Y=8/5x-3.
Start at -3 on y axis and go down 8 points and right 3.
first is distributive property
next is the subtraction property of equality
then you simplify
finally you use the division property of equality
hope this helps
