Which of these graphs is the solution set for the equation y = -3x - 2?

Answers

A because y=-3x-2 has these transformations
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation

Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2

P.S. wouldn't mind getting brainliest

Answer:

Step-by-step explanation:

Frist you find negative 2 and you can see that 2 are going there so you need to find where negative 3 is when you add negatives they trun into a possitve so go up 3 times from negative 2.

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3

Answers

Ccccccccccccccccccccc

The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.

What is the equation?

More than one variable may be present inside a linear equation.

An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given equation,

13 = -3 + z

Since, A + B = B + A

Thus, -3 + z can be written as z - 3

So, 13 = z - 3

Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".
