Step-by-step explanation:
the general equation of a line is
y = ax + b
a is the slope of the line.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b :
6 = -3×4 + b = -12 + b
18 = b
so, the full line equation is
y = -3x + 18
which is answer C : 3x + y = 18
Answer:
is the option a) x^6y^5
Step-by-step explanation:
Answer: I really don't know how to do this sorry
Step-by-step explanation:
9n = 3n-12
-3n= -3n
6n= -12
divide by 6 = -2 =n
to check.. 9 times -2 = -18 soo.. 3 times -2= -6-12= -18
so it is correct!!
hope it helps :)
First, add all the numbers together. 
Divide by the amount of numbers. 
is the closest, so that is the answer.
