Step-by-step explanation:
(y2-y1)/(x2-x1)
Plug coordinates into that
Then plug one of the coordinates into y = -3x+b to get b
180=2x+y
180-y=2x
(180-y)/2=x
Answer:
C. 4.2a + 0.8
Step-by-step explanation:
Given:
The two binomials given for addition are:
and 
Now, adding both the binomials, we get:

Distributing the positive sign inside the second binomial, we get:

Now, combining like terms using the commutative property of addition, we get:

Simplifying the above expression, we get:

Therefore, the resulting addition of the given binomials is 
Hence, option C is the correct answer.
