For this case we have the following equation:
Let 
We have:
By definition, given an equation of the form 
The quadratic formula, to find the solution can be written as:
In this case we have:
Substituting in the quadratic formula we have:
See attached image
Answer:
Option B
I believe you would do 2 times 3, which gives you 6. 3 is for the number of coin tosses, and 2 is the number of sides of a coin.
-3 is the y intercept, remember y=mx+b.
b is always the y intercept.
rewritten this equation would look -18=4x-3
Answer:
-1/3
Step-by-step explanatition
the slope goes down to the right, so it is negitive. It goes down x by 3, and down y by 1. slope = y/x , slope = -1/3
