Answer:
A
Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are and
.
To find the constant of proportionality, all we have to do is divide any value of by its corresponding value of
. Let's take the values in the first row of the table. We know that
and
, so the constant of proportionality is
. Hope this helps!
Answer:
0.512 goals per game
Step-by-step explanation:
Given:
The number of games is represented by 'x' and number of goals is represented by 'y'.
Now, 'y' varies directly with x and at a constant rate.
A direct relationship line is given as:
Where, 'm' is the constant rate of change.
Now, for
So, a point on the line is given as (82, 42).
Plug in the given values in the above equation and solve for 'm'. This gives,
Therefore, Keith scores at a constant rate of 0.512 goals per game.
