The equations are given in the following form:

where:
m=slope
b =y-intercept
All of the equations given have a Y intercept of 4, so just looking at the
Y-intercept stills leaves all the equations as possible answers. So we have to
use the X intercept. What is the X-intercept you may ask? That is the point where the Y value of the equation is 0.
So, the question is, for what equation does a value of x=6 result in y=0?
You can see that (d) is the correct answer::

Simplifying this shows that y=0:

x-int = A
y-int = B
--> Bx + Ay = A*B
-------
4x + 6y = 24
