To be parallel, this new line has to have the same slope as the other. To find the slope, we look at the number multiplying x.
-x means x is being multiplied by -1, so the slope, or m, is -1.
y = -x + b
Now, input the coordinate point and solve for b.
-2 = -1(2) + b
-2 = -2 + b
Add 2 to both sides.
0 = b
y = -x
Answer:
Step-by-step explanation:
B, y=5x

Answer: Choice C</h3>
Work Shown:
In the third step, I used the rule that 
. You subtract the exponents when dividing exponents of the same base.
After that, I used the rule 
which is the same as saying 
to end up with choice C as the answer.
So first you would do y-y over x-x so it would be 3-12 over 4-7 which equals -9/3 so which is -3
You now plug it into y-3= -3(x-4) which equals y=-3x+15 so your b=15
Commutative:
a+b+c=a+c+b
1.3+23.4+3.4=23.4+1.3+3.4
Associative:
(a+b)+c=a+(b+c)
(1.3+3.4)+23.4=1.3+(3.4+23.4)
