Answer:

Option 1) -7

Step-by-step explanation:

Given : The equation shows the relationship between x and y : $y=-7x+9$

To find : What is the slope of the equation?

Solution :

The general slope form of the equation is $y=mx+b$

Where, m is the slope and b is the y-intercept.

Now, We compare the given equation with general form of the equation

$y=-7x+9$

On comparing, m=-7 and b=9

So, The slope of the given equation is -7.

Therefore, Option 1 is correct.

In y = mx + b form, the slope will be in the m position

y = mx + b
y = -7x + 9

notice that in the m position, the number is -7. That means ur slope = -7

If the basic measuring unit in base-7 is 49 circles, what does the measuring unit of size .001seven look like

Serjik [45]

The measuring unit is the standard unit of a quantity

The measuring unit of size 0.001 is represented by one millionth circle

<h3>How to determine the unit of base 0.001</h3>

The basic measuring unit in base 7 is given as:

49 circles

The above can be represented as:

Base 7 = 49 circles

Represent the base with n.

So, we have the following rule

$Circle = n^2$

For measuring unit 0.001, we have:

$Circle = 0.001^2$

Evaluate the square

$Circle = 0.000001$

This means that,

The measuring unit of size 0.001 is represented by one millionth circle
