The qualities x and y are proportional.
find the constant of proportionality (r) in the equation y= rx

r = 1/3

Step-by-step explanation:

The constant r must remain the same for all pairs of x and y that we use.You can apply any pair of values from your question..then substitute the values into the equation

If x = 15 and y = 5...then;

;5 = 15r...then divide both sides by 15

; r = 5/15then reduce it to its lowest terms..by dividing the numerator and the denominator with 5

; r = 1/3

Or take the pair of,

x = 33 and y = 11

;11 = 33r...then divide both sides by 33

;r = 11/33...then reduce it to the lowest terms by dividing the numerator and denominator with 11

;Hence r..still remains as 1/3

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
