Answer: The decimal 0.88888.... represented by the fraction 
Step-by-step explanation:
Since we have given that
0.888888....
So, Let x = 0.88888....=
-----(1)
Now, multiply by 10 on both sides, we get that

Now, Subtracting (1) from (2), we get that

Hence, the decimal 0.88888.... represented by the fraction

Is this math cause I'm tryna figure it out
Answer:

Step-by-step explanation:
A line in 2-dimensional space has the following general equation:

Where m is the slope of the line, and b just a number
the slope can be obtaine using th following formula:

The point 2 is the one with the smallest value for x, that is (-10,-7) and the Point 1 is any other that belongs to the line, in this case, (-5,-9)

Resulting that 
To find the other term we can use any other point, I prefer us the first one so...
We have the following equation:

Resulting that b=18
I just have to eval the point (-10,-7) in the equation stated at the beginning knowin that m was calculated previously.
