Question

Find k, the constant of proportionality, for the data in this table. Then write an equation for the relationship.

They equation needs to be in the form y=kx

K=

Equation:

Answer 1

Answer:

see explanation

Step-by-step explanation:

The equation of proportionality is

y = kx ← k is the constant of proportionality

k = y ÷ x, thus

k = 160 ÷ 25 = 320 ÷ 50 = 480 ÷ 75 = 640 ÷ 100 = 6.4

and

y = 6.4x ← equation of proportionality
