It must be a horizontal line, as the speed doesn't alter.

#### Explanation:

The object covers a distance of 16 - 4 m in 6 - 1 sec i.e. It goes 12 m in 5 sec.

As $s p e e d = \frac{\mathrm{di} s \tan c e}{t i m e}$

Speed = $\frac{12}{5}$ = 2.4 m/s

So, yes it is a straight line, but it must also be horizontal at 2.4 units up the y axis.
