1. D. He paid total of $1080
2. (810-1080)/(6-0) = -45
The slope is -45
3. Slope means how much less he owes per month
For this, you need the pythagorean theorem, which is

Your a is 12, and your b is 35. Now you can solve for c, which equals 37 miles.
Y = Total
x = the amount of text messages sent
The equation is : y = 0.50x + 20
X | Y
1 | 20.50
5 | 22.50
10 | 25
(1,20.50)
(5,22.50)
(10,25)
