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:
1/6
Step-by-step explanation:
If you graph your points on a coordinate grid, you will see the rise/run. From the point -4, -3 to the point 14,0 ; there is a rise of 3 and a run of 18. The rise goes over the run and creates a fraction of 3/18 and 3/18 simplified is 1/6! Hope this helps!
Answer:
69 yards
Step-by-step explanation:
Perimeter = 2(length + width)
300 = 2(81 + width)
150 = 81 + width
width = 69
The answer is 3. 4 because 4 doesn’t have a variable :)
A=p(1+r/100)^n
A=2500(1+4/400)^16
A=2931.45
