Answer:

She needs to add no fertilizer, option A)

Step-by-step explanation:

Equation of a Line:

According to the conditions of the question, being x the ounces of fertilizer Olivia adds to the soil, and y the number of blooms each rose bush has, the relation between them is

[tex]y = 1.345x + 4[/tex]

It's bee required to compute the value of x such that the roses have 4 blooms, thus

[tex]1.345x + 4=4[/tex]

Solving for x

[tex]1.345x=4-4=0[/tex]

[tex]x=0[/tex]

This means she needs to add no fertilizer, option A)

Answer:

A)    When she adds no fertilizer.

Step-by-step explanation:

Since 4 is the y-intercept the x-value must be 0. This only happens when she adds no fertilizer..
