What is the y-intercept point of the line 3x - 2y = 12?

Answer and explanation

Correct answer: (0, -6)

The governing concept is finding an axis intercept from a linear equation. Every point on the y-axis has x-coordinate 0, so substitute x=0 into 3x−2y=12. This gives 3(0)−2y=12, hence −2y=12 and y=−6 after division by −2. Therefore the y-intercept is (0,−6), making option B correct. The sign matters: substituting (0,6) gives −12 on the left, not 12, so option A fails. If y=0 is substituted instead, then 3x=12 and x=4, giving (4,0), the x-intercept represented by option C. Option D has the wrong axis intercept and also does not satisfy the equation. Checking the selected point directly confirms 3(0)−2(−6)=12.
