Which line has slope (0) and (y)-intercept (-4)?
Answer and explanation
Correct answer: \(y=-4\)
A line is written as \(y=mx+c\), where \(m\) is the slope and \(c\) is the \(y\)-intercept. Here, \(m=0\) and \(c=-4\), so \(y=0x-4=-4\). Option C has a \(y\)-intercept of \(-4\), but its slope is \(4\), not zero. Exam tip: A line with zero slope is always horizontal.
