Answer:
n = -1
Step-by-step explanation:
So first subtract 9 to both sides
8n = -n - 9
Now you want the n on one side and the constant on the other
so add the single n to the n side
9n = -9
Divide 9 to both sides to solve for n
n = -1
Answer:
Step-by-step explanation:
y=mx+b
so inset the first point into the equation
-3 for x and 7 for y.
7=m(-3)+b
y=mx+b
1 for x and -1 for y
-1=m(1)+b
now put them together and solve for m and b.
-1=m+b
7=-3m+b
--------------------
-1-b=m
7=-3m+b
inset m into the equation
7=-3(-1-b)+b
7=3+3b+b
4=4b
b=1
--------------
insert b back in for -1=m+b
-1=m+1
m=-2
---------------------------------------
Now insert it back into y=mx+b
y=(-2)x+1
so this line contains those points that were given
Hope this helps :)
Since they are collinear, it means the BFD is a straight line and all the angles formed by the lines resting on a straight line add up to degrees. So,
When we add and we get . So,
Henceforth, or angle is equal to degrees. :D
