Consider the equation y = 4.2x and the table below that represents this relationship.

A 2-column table with 4 rows. Column 1 is labeled x with entries 0, 2, 4, 6. Column 2 is labeled y with entries 0, 8.4, 16.8, 25.2.

The coefficient of the equation or constant of proportionality is
.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In this problem we have

The constant of proportionality K is the same that the slope of the linear equation

The value of k is

5y

step-by-step explanation:

the answer

b. they are parallel and will never intersect.
