Answer:

y = - 2x - 10

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 )

Here m = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute (- 6, 2) into the partial equation

2 = 12 + c ⇒ c = 2 - 12 = - 10

y = - 2x - 10 ← equation of line

All sides of a square and a pentagon are 9 inches long. Are their perimeters the same? Explain

EastWind [94]

No they wouldn't be the same because, the perimeter is adding all sides.

The square has 4 sides so you would add 9, four times.

9 + 9 + 9 + 9 = 36

And a pentagon has 5 sides so you would add 9, five times.

9 + 9 + 9 + 9 + 9 = 45

So, they are not the same.

Hope this helps. :)

Which explains why the graph is not a function?

The statements that apply to the ratio of rice and water are:

The ratio of rice to water is 1 to 2.5
The ratio of water to rice is 2.5 to 1

<h3>Ratios</h3>

Ratios are used to compare quantities of different measurements

The entries on the table are given as:

<u>Rice Water</u>

2 5

3 7.5

5 12.5

8 20

<h3>The ratios of both quantities</h3>

The ratio (r) of rice and water is then calculated as:

$r = \frac{Water}{Rice}$

Pick any corresponding table entry.

So, we have:

$r = \frac{5}{2}$

Divide

$r = 2.5$

This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1
