What is the (y)-intercept of (6x-4y+12=0)?
Advertisement
Answer and explanation
Correct answer: 3
To find the y-intercept, put x=0. Then -4y+12=0, so -4y=-12 and y=3. Hence, the line crosses the y-axis at (0,3), and its y-intercept is 3. The value -3 may result from a sign error. Exam tip: always set x=0 to find the y-intercept.
