Explanation:

Equation of the position a car which follows a rectilinear path is given as

x/y=1/6+1/(-2)t

Starting point is given by equation for t=0. To meet the condition we get

x/y=1/6+1/(-2)xx0
=>x/y=1/6

From the expression we see that starting point, out of the given choices, is

(x,y)=(1,6)
