What is the slope of the line represented by the equation f(t)=2t−6?

A linear equation is often written in slope-intercept form as f(t) = mt + b, where m is the slope and b is the y-intercept. In f(t) = 2t − 6, the coefficient of t is 2, so the slope is 2, and the constant term is −6, so the y-intercept is −6. This matches choice A.
