Answer:

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Write the equation of the line that goes through the point (−9, −4) and is parallel to the line −x + 3y = −0.5

inysia [295]

Answer:

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

Explanation:

Given

Parallel to: $-x + 3y = -0.5$

Passes through (-9,-4)

Required

Determine the line equation

First, we calculate the slope (m) of the said line

$-x + 3y = -0.5$

Make y the subject

$3y = x - 0.5$

Divide through by 3

$y = \frac{1}{3}x - \frac{0.5}{3}$

An equation has the general form:

$y = mx + b$

Where

$m = slope$

So:

$m = \frac{1}{3}$

Because the required line is parallel to $-x + 3y = -0.5$ , then they have the same slope of $m = \frac{1}{3}$

Next, is to calculate the line equation using:

$y = m(x - x_1) + y_1$

Where

$m = \frac{1}{3}$

$(x_1,y_1) = (-9,-4)$

This gives:

$y = \frac{1}{3}(x -(-9)) + (-4)$

$y = \frac{1}{3}(x +9) -4$

Open bracket

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

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