Answer:
The equation of the proportional relationship can be written as y = (2/3)x.
Explanation:
This equation is derived by using the fact that the slope of the relationship between x and y is 2/3. The slope of a line can be expressed as the ratio of the change in y to the change in x, which is represented by (delta y) / (delta x).
Since the slope is 2/3, the change in y for a unit change in x can be expressed as 2/3 * x. This relationship can then be written in terms of x and y by solving for y:
y = (2/3) * x.
In this equation, y is directly proportional to x with a constant of proportionality equal to 2/3.
