Answer:
The average plant height is not changed by the amount of multivitamin.
Explanation:
Looking carefully at a graph of x as a function of y, we can see how the Y-axis variable, the average plant height, in this case, changes as a function of the X-axis variable, in this matter the amount of multivitamin (mg). So if the relationship between these two variables is defined by a straight line, it means that the average plant height is not changed by the amount of multivitamin.
