This graph shows a proportional relationship. What is the constant of proportionality?

Enter your answer as a decimal in the box.

k = 13.8

Step-by-step explanation:

y = kx where 'k' is the constant of proportionality

'k' can be found using the same method for finding slope

(82.8-27.6) ÷ (6-2)

55.2 / 4 = 13.8

(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)

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
