In the line (y=7-10x), what are the slope and (y)-intercept?

Answer and explanation

Correct answer: Slope
-10, y-intercept 7

Compare the line with slope-intercept form \(y=mx+c\). Since \(y=7-10x=-10x+7\), the coefficient of \(x\) is \(-10\), so the slope is \(-10\); the constant term is \(7\), so the y-intercept is \(7\). Option C has the correct y-intercept but misses the negative sign of the slope. Exam tip: in \(y=mx+c\), \(m\) is the slope and \(c\) is the y-intercept.
