Answer: 
Step-by-step explanation:
You have the equation 
.
Then, to solve for the variable 
from the equation you need:
Make the subtraction of the right side of the equation:
(As the denominators are 1 and 
, the least common denominator is )
Multiply to both sides:
Add 
to both sides:
And finally divide both sides by 
:
Answer:
m = 0.36666666666667
Step-by-step explanation:
im not sure if im correct.
Let's set up an equation.
so we know the answer is -13.
1/3 of a number (our variable) can be written as 1/3n.
8 less than that would be subtracting 1/3n by 8
so we have -13 = 1/3n - 8.
To solve:
Add 8 to both sides: -5 = 1/3n
Multiply both sides by 3 (to cancel fraction): -15 = n
You can check by plugging -15 into the equation we made.
Answer:
Slope is undefined.
Step-by-step explanation:
Slope of 0 is a horizontal line.
Slope of undefined is a vertical line.
Any other slope is something in between.
