In the line (y=24-6x), what are the slope and (y)-intercept?
Answer and explanation
Correct answer: Slope -6, y-intercept 24
Compare the equation with slope-intercept form \(y=mx+c\). The given line can be written as \(y=-6x+24\). Thus, the coefficient of \(x\), \(-6\), is the slope, and the constant term, \(24\), is the y-intercept. Option B has the correct intercept but misses the negative sign in the slope. Exam tip: In \(y=mx+c\), \(m\) is always the coefficient of \(x\).
