(3, -5)(0, 4)<br> Write the equation of a line using the point slope formula
Serga [27]

Answer:

y = - 3x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (0, 4)

m = \frac{4-(-5)}{0-3} = \frac{4+5}{-3} = \frac{9}{-3} = - 3

The line crosses the y- axis at (0, 4) ⇒ c = 4

y = - 3x + 4 ← equation of line

Olivia is growing roses and keeps track of how much fertilizer (in ounces) she adds to the soil and how many blooms each rose bu
dusya [7]

Answer:

<em>She needs to add no fertilizer, option A)</em>

Step-by-step explanation:

<u>Equation of a Line:</u>

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

y = 1.345x + 4

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

1.345x + 4=4

Solving for x

1.345x=4-4=0

x=0

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