Is 8 3/4 gal bigger or smaller than 32 qt

A pint is not bigger than a quart. A pint is half the size of a quart, and it contains 16 ounces or 2 cups. 

It must have the same slope as the given line, so

m = -A/B = -1/-2 = 1/2

So far, we have

y = mx + b = x/2 + b

Use the given point to find b.

4 = -2/2 + b = -1 + b

b = 5

y = x/2 + 5

Multiply through by 2.

2y = x + 10

Standard form:

x - 2y = -10
