What is the slope of the line \(y=-4x+9\)?

Answer and explanation

Correct answer: \(-4\)

In the standard form \(y=mx+c\), the coefficient of \(x\), namely \(m\), is the slope. For \(y=-4x+9\), \(m=-4\), so the correct answer is \(-4\). Option \(4\) has the wrong sign, while \(9\) is the y-intercept, not the slope. Exam tip: In \(y=mx+c\), identify the coefficient of \(x\) directly.
