-1/2w-3/5=1/5w
-5w-6=2w
-5w-2w=6
-7w=6
w = -6/7

Hope this helps, you can look it up on google by the way ^^
For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cutoff point with the y axis
We need two points through which the line passes to find the slope:

We found the slope:

So, the equation is of the form:

We substitute a point to find "b":

Finally, the equation is:

Answer:
Option D
He would need less than 8. So he would need 2.5 pints. I think.
