Answer:
the equation of the line is 7x + y = 0 .
Step-by-step explanation:
in the standard form of the line that is Ax +By = C we can write it in the form of
By = C - Ax

which is in the form of 
where m is the slope of the line and c is y intercept made by the line.
comparing
and 
we get that
and 
since it is given that slope of the line is -7 therefore m = -7 and c = 0
therefore
and 
therefore C = 0 , A = 7 and B = 1
therefore the equation becomes 7x + y = 0
<span> The distributive property is a special way where multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as:

<span>a(b + c) = ab + ac.

Does this help in any way?

Answer: C
Step-by-step explanation: since the x’s are common terms, you just add them together
