Answer:

3x - y + 5 = 0

Step-by-step explanation:

When two points are given and the equation of the line passing through those points are asked we use two - point form to determine the equation of the line.

Two - point form: $ \frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 -x_1} $

Here the two points are: (2,11) & (-8,-19).

Let $ (x_1,y_1) = (2,11) $ and $ (x_2, y_2) = (-8,-19) $

Substituting in the formula we have:

$ \frac{y - 11}{-19 - 11} = \frac{x - 2}{-8 - 2} $

$ \implies \frac{y - 11}{-30} = \frac{x - 2}{-10} $

Simplifying we get:

y - 11 = 3x - 6

⇒                                       3x - y + 5 = 0

Y-intercept (0, 1)
Equation of asymptote y=0

Equation of asymptote can also be called horizontal asymptote.
It means the place where the line almost meets but actually not touching the place. The line almost touches y=0 but it actually does not touch it.

a shipping company makes a display to show how many cubes can fit into a large box. each cube has a side of 2 inches. the large
ehidna [41]

1 The volume of the cube is 2 * 2 * 2 or 2 ^ 3 in ^ 3 while the volume of the large box is 10 * 10 * 10 or 10 ^ 3 in ^ 3.

2 The answer is 125. Just divide the large box to the volume of the cube 1000 / 8 = 125.

3 The box will hold the same number of balls as small boxes. With the balls, there is empty space.

4 The answer is still 125. Just find the volume of the box and of the cube. Divide the box volume by the cube volume.
