Hi...
By observation, we can see y is POSITIVE when x is 0 ....A out
Also X is POSITIVE when y is 0....D and E ARE out...
Substitute the values as 0 to get above statements

Now between B and C..
When y=0, x>3..
B. 2x+4y=8.....2x+4*0=8.....x=4... Possible
C.4x+2y=8.......4x+2*0=8....x=2....NO

Ans B

The line passes through (4, 0) and (0, 2). Its equation will be

y - 0 = (2 - 0)/(0 - 4) * (x - 4)
-2y = x - 4
x + 2y = 4
which is the same as 2x + 4y = 8

Answer (B)

From the diagram, we can see the y intercept > 1 (+ve) & x intercept >3 (+ve)

convert the equation in the options in intercept form i.e.
x/a + y/b = 1, where a is the x intercept & b is the y intercept

As is eveident from problem stmt, a,b are positive hence only 2 options remain

I need to find an option which has a > 3 & b >1

=> x/4 + y/2 =1
