Step-by-step explanation:

3x - 2y = 12

Substituting y = 9, we find:

$3x - 2 \times 9 = 12 \\ \therefore \: 3x - 18 = 12 \\ \therefore \: 3x = 12 + 18 \\ \therefore \: 3x = 30 \\ \therefore \: x = \frac{30}{3} \\ \therefore \: x = 10 \\ \therefore \: A (...., 9) = A (10, \: 9)$

Similarly, solving for point B (4, __) =B (4, 0)
