What is the slope of the line \(3x+2y=12\)?

Answer and explanation

Correct answer: \(-\frac{3}{2}\)

Rearranging the equation gives \(2y=-3x+12\), so \(y=-\frac{3}{2}x+6\). In the slope-intercept form \(y=mx+c\), the coefficient of \(x\) is the slope; hence the slope is \(-\frac{3}{2}\). Option B has the wrong sign. Exam tip: For a line \(ax+by+c=0\), its slope is \(-\frac{a}{b}\).
