If this is algebra, for example, please label the School Subject correctly. Otherwise the correct teacher may never read your post.

3X + 5Y = K.

k = A * B = 3 * 5 = 15.

3 and 5 are now factors of 15.

Therefore, 15 is divisible by both:

3X + 5Y = 15,

Let X = 0,

3*0 + 5Y = 15,

5Y = 15,

Y = 3 = Y-Int.

Let Y = 0,

3X + 5*0 = 15,

3X = 15,

X = 5 = X-Int.

Graph: (0 , 3) , (5 , 0).
