Y = 4x/3 – 7

3 + 9t

Excluded because x is even when t is odd

3 + 18t

(3(3 + 18t) + 1)/2 = 5 + 27t

Excluded when t is even

21 + 36t

(3(21 + 36t) + 1)/4 = 16 + 27t

Excluded when t is odd

21 + 72t

(3(21 + 72t) + 1)/8 = 8 + 27t

Excluded when t is odd

21 + 144t

(3(21 + 144t) + 1)/16 = 4 + 27t

Excluded when t is odd

21 + 288t
