ANSWER
y = x + 7
EXPLANATION
We want to use the two points to form a linear equation in slope-intercept form.
That is in the form:
y = mx + c
To do this, we first find the slope by using formula:

where (x1, y1) = (3, 10)
(x2, y2) = (6, 13)
So, we have that:

The slope, m, is 1.
Now, we use the point-slope formula to find the equation. That is:

That is the answer.
1/3=.33333333, which is 33%
we know that
1 gal.= 3.8L
we can also write as
3.8L=1 gal
Firstly, we will find for 1L
so, we can divide both sides by 3.8


now, we will multiply both sides by 22



so, option-b.............Answer
