write an equation that defines a line that is parallel to the line y = 2/3x + 4?

A line that is parallel to the line y = (2/3)x + 4 will have the same slope. The slope of the line is 2/3.

So, the equation of the line that is parallel to y = (2/3)x + 4 can be written as y = (2/3)x + b, where b is the y-intercept of the line.
