Answers:
The unit rate is 8/3
The graph is a straight line through the points (0,0) and (3,8)
===========================================================
Further Explanation:
Each time d increases by 8, t increases by 3
unit rate = slope = (change in d)/(change in t) = 8/3
-----------
All direct variation equations are straight lines that go through the origin (0,0)
Starting at the origin, move 3 units to the right and 8 units up to arrive at (3,8)
Therefore, this straight line goes through the two points (0,0) and (3,8)
If you were to apply the slope formula to these two points, then you should find that m = 8/3 to confirm the previous section's answer.
