There is a 1/4 chance of landing on a 1...

So, 25% is an UNLIKELY chance.

Let's list the possibilities...

So a total of 15 possibilities.

Check this:

2)

Certain is 100% or 1, so E is certain.

Impossible is 0, so A is impossible.

Even is 50%, so C is even.

When moderators need to check it, I think..... I dunno... it happens to me sometimes.

We can factor this by finding the GCF of the numbers.

=117x3−351x2−52x+156

=13(3x+2)(3x−2)(x−3)

Formula for slope:

y=mx+b
-5=(9/8)(9)+b    
-5=81/8+b
-5-10 1/8=b    
-15 1/8=b

Now we can substitute b into our equation.

So, y=(9/8)-15 1/8 will be our answer!

AnExtremelyLongName is correct! You can also check out the answer here:

AnExtremelyLongName fixed EP's mistake, so you can solve it now!

4) A HORIZONTAL line's slope is unchanging, so the slope is 0.
