Answer:

  -4

Step-by-step explanation:

In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).

Here, the coefficient of x is -4.

The slope is -4.

_____

<em>Additional comment</em>

Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...

  y = kx . . . . . with no added constant

"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):

  y = mx + b

Can I please get some help with this
algol [13]

Answer

x= -3  -> y= -2

x= -1 -> y= -4

x= 3 -> y= -2

Step-by-step explanation:

The lines around the x in the equation is the absolute value symbol.

If you put a positive in, it stays positive.

If you put a negative in, it becomes positive.

Then solve normally.

Good luck!

Suppose the coefficient matrix of a linear system of three equations in three variables has a pivot in each column. Explain why
Elis [28]

The system has a unique solution. Because the augmented matrix can be reduced to the form of the identity matrix.

<h3>What exactly is a linear system?</h3>

It is an equation system in which the maximum power of the variable is always 1. A figure with only one dimension and no breadth. It is made up of infinite dots placed side by side.

The augmented matrix must be reduced to the form of the identity matrix since there are three pivots one in each row.

Whatever is on the opposite side of the equal sign, there is a solution that is specific and exists.

Hence, the system has a unique solution.
