The answer is the first option. 7 left is not - 7 in this case. With these questions, you switch the signs. The vertical movement signs stay the same. Therefore, the answer is the first option.
Step-by-step explanation:
u just have to draw a graph nd start at -2 which goes down -2 twice then go up 4 over 1 nd u just connect the lines nd find the slope of the lines that's how I learned it

Answer:
All Real Numbers Are Solutions
Explanation:
9x + 27 = 9(x + 2) + 9
- <u>Simplify both sides of the equation.</u>
9x + 27 = 9(x + 2) + 9
9x + 27 = (9)(x) + (9)(2) + 9 (Distribute)
9x + 27 = 9x + 18 + 9
9x + 27 = (9x) + (18) (Combine Like Terms)
9x + 27 = 9x + 27
9x + 27 = 9x + 27
- <u>Subtract 9x from both sides.</u>
9x + 27 − 9x = 9x + 27 − 9x
27 = 27
- <u>Subtract 27 from both sides.</u>
27 − 27 = 27 − 27
0 = 0
<u>Therefore, all real numbers are solutions.</u>
