Two points on this graph are (40, 80) and (70, 90). These points can be used to find the slope.
The formula for slope is (y2-y1)/(x2-x1).
Plugging our numbers into the formula:
(80-90)/(40-70) = (-10)/(-30) = 1/3

Algebra

$\frac{1}{2} (8y - x + 12) = a$

Divide everything by two, or times everything by 1/2.

$4y - \frac{1}{2} x + 6 = a$

This is as far as you could go due to no like-terms.
