The line 2x - 3y = 12, meets x-axis at point A and y-axis at point B, then :
A = (6, 0) and B = (0, -4)
A = (0, -4) and B = (6, 0)
A = (0, -4) and B = (-6, 0)
A = (-6, 0) and B = (4, 0)

Answer
We know that,
y-coordinate at x-axis = 0.
Let point A be (a, 0).
Since,
Line 2x - 3y = 12 meets x-axis at point A.
∴ Point A(a, 0) satisfies the equation 2x - 3y = 12.
⇒ 2a - 3(0) = 12
⇒ 2a - 0 = 12
⇒ 2a = 12
⇒ a = = 6.
∴ A = (a, 0) = (6, 0).
We know that,
x-coordinate at y-axis = 0.
Let point B be (0, b).
Since,
Line 2x - 3y = 12 meets y-axis at point B.
∴ Point B(0, b) satisfies the equation 2x - 3y = 12.
⇒ 2(0) - 3b = 12
⇒ 0 - 3b = 12
⇒ -3b = 12
⇒ b = = -4.
∴ B = (0, b) = (0, -4).
Hence, Option 1 is the correct option.
