A small business estimates that the value V(t) of a copy machine is decreasing according to the function V(t)=4000(4)^0.13t

where t is the number of year's that have elapsed since the machine was purchased and V(t) is in dollars. ​

Aline is perpendicular to another line m2= (-1/m1), where m1 is the slope of the original line and m2 is the slope of the perpendicular line. which of the following equations represents the line that passes through the point (-2,1) and is perpendicular to the line below?
