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.

Answer:
He would need to run 5/12 more miles to reach his goal.
Step-by-step explanation:
You want to get all your fractions to the denominator of 12.
1/2 = 6/12
1/4 = 3/12
2/3 = 8/12
Then you would want to add them all up, 6/12+3/12+8/12 = 17/12.
Then you subtract his goal of 22/12-17/12, to get your answer of 5/12.
Hope this helps! :)
