OH MA GOSH THANK YOU SOOO MUCH DAMON
You are welcome.
thank you so much
To find the constant of proportionality (r) in the equation y = rx, we need to use the given proportional relationship between x and y.
In a proportional relationship, the ratio between the values of x and y remains the same. We can find this ratio by dividing any two corresponding values of x and y.
Let's choose the first pair of values: x = 5.85 and y = 5.85.
To find r, we divide y by x:
r = y / x = 5.85 / 5.85 = 1
So, the constant of proportionality (r) in this case is 1.
In general, for any proportional relationship, the constant of proportionality (r) is obtained by dividing the value of y by the value of x for any given pair of corresponding values.
