Question

Suzie solved a linear equation for y. This equivalent equation was her result. y = 7x + 23 Which equations could have been the linear equation Suzie manipulated? Check all that apply.
1. y + 7x = 23 2. –7x + y = 23


3. 2y – 14x = 46 4. y – 7x = –23 5. 7x – y = –23

Answer 1

Answer:

2, 3, 5

Step-by-step explanation:

The question asking for the linear equation Suzie manipulated. The answer should be equal to the starting equation. So, we just need to manipulate the option to y= mx + c format.

1.  y + 7x = 23

y=  -7x +23 (false)

2. . –7x + y = 23

y= 7x + 23 (true)

3. 2y – 14x = 46

2y= 14x+ 46

y= 7x +23 (true)

4. y – 7x = –23

y= 7x - 23 (false)

5. 7x – y = –23

-y= -7x -23

y= 7x + 23 (true)
