Lol I answered your last question
Answer:
B. 
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:


Then use the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done faster that way. It does not matter which ordered pair you choose:
−9 = 3 + b
−12 = b

________________________________________________________________________________________________
−5 = 7 + b
−12 = b

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.
I am joyous to assist you anytime.

It goes times add 3 and then this pattern repeats.
(x^2 - 4^2)^2 = x^4 - 4^4
(x^4 - 4^4) (x^2 + 4^2) = x^2 - 4^6
The Angela's solution is wrong cause when you multiply you get a different answer.
<span>(x - y + 1) - (x + y - 1)
x - y + 1 - x - y + 1
= (x - x) + (y - y) + (1 + 1)
= -2y + 2
In short, Your Answer would be: -2y + 2
Hope this helps!</span>
