What is the (y)-intercept of the equation (2x+3y=12)?
Advertisement
Answer and explanation
Correct answer: 4
To find the y-intercept, put x=0. Then 2(0)+3y=12, so 3y=12 and y=4. Hence, the line meets the y-axis at 4, so the correct answer is 4. The number 12 is only the constant in the equation, not the y-intercept. Exam tip: always set x=0 to find the y-intercept.
