will.h · Answer

Since x axis reflects the number of hours 
then let's track the lines.. 
from 0 to 2 that means it was in motion for 2 hrs (according to the constant amount of increase) 
then went to horizontal line for 1 hr then back again in motion for 2 hrs

yes i understand the first answer.. but whats this one? http://prntscr.com/dizb1e

will.h · Answer

This is a linear equation/function 
Thus what we need to find is the slope

pick any 2 point from the graph 
(0,80)(1,120)
Slope = y2-y1/x2-x1
Slope = 120 - 80/1-0
Slope = 40/1
Slope = 40

Thus the answer is D

will.h · Answer

initial value is normally the y intercept 
the y intercept is when the x = 0

when x = 0 the y value is 4 and since y axis represent the distence then the answer would be C
