What is the y-intercept of the equation \(3x+y=15\)?
Answer and explanation
Correct answer: \((0,15)\)
To find the y-intercept, put x=0 in the equation. Then \(3(0)+y=15\), so y=15 and the point is \((0,15)\). Option A is the x-intercept because it is obtained by putting y=0. Exam tip: every point on the y-axis has x-coordinate 0.
