Suzie solved a linear equation for y. This equivalent equation was her result. y = 7x + 23 Which equations could have been the l inear 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
1 answer:
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)
