Having a look at the graph, we will find that:
For speed: it is increasing along the x-axis
For height: it is increasing along the y-axis
This means that the function is linearly increasing.
Based on this, the correct choice would be:
D. As speed increases, height increases
E) distributive property
Because you are distributing the 3 to 2/5x and 7/5y
V=BH/3
V=(4)(6)/3
V=(24)/3
V=8
