Answer:

y = - \frac{4}{3} x - 1

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, 3) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line

m = \frac{-1-3}{0+3} = - \frac{4}{3}

The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

y = - \frac{4}{3} x - 1 ← equation of line

-0.85-0.85+-3.9=-8.15
gregori [183]
<h2>False</h2>

Due to the fact that the answer we got here is incorrect, this statement is false.

First, subtract -0.85 and -0.85, we get:

-1.7

Then, add -1.7 and -3.9, we get:

-5.6

It is important to note that the answer in the statement is written as “-8.15” which is incorrect.

The correct answer is -5.6

This is why the answer is

<h3>False</h3>

<em>Hope this helps :)</em>
