If the two lines (y=(q-9)x+14) and (y=12x-6) have the same slope, what is (q)?

Answer and explanation

Correct answer: 21

In the form \(y=mx+c\), the coefficient of \(x\) is the slope \(m\). The slopes of the first and second lines are \(q-9\) and \(12\), respectively. For equal slopes, \(q-9=12\), so \(q=21\). If 20 were chosen, the first slope would be 11, not 12. Exam tip: for parallel lines or lines with equal slopes, compare the coefficients of \(x\).
