Answer:
47
Step-by-step explanation:
The constant rate is defined as
[tex]r=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Where [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] are two points on the line.
Let's use points (0,0) and (6,282).
[tex]r=\frac{282-0}{6-0}=47[/tex]
Therefore, the constant rate of from the graph is 47.
So, the right answer is the third choice.
