Question

Which line has a constant of proportionality between

\[y\] and
\[x\] of

\[\dfrac{4}{3}\]?

Answer 1

The line that has a constant of proportionality between y and x of 4/3 is the Green Line or Line B.

How the constant of proportionality is determined:

The constant of proportionality is the unit rate or the rate of change that defines a linear or straight-line relationship between two variables.

Based on the graph lines of the attached graph, we know that when y of the Green (B) Line increased to 4, x increased to 3, unlike Lines A and C.

Thus, we can conclude that the Line B has a constant of proportionality between y and x of 4/3.
