The US postal service delivered 7.14 x 1010 pieces of mail in the month of December 7.14 x 1010=7211.4
3.21 x 1010 in the month of January. 3242.1
What is the total mail delivered for these two months?

+ 3242.1
__________
10453 .5 TOTAL MAIL
As x increases from 9 to 12 (a change of 3), y increases from -2 to 0 (a change of 2). Thus, the slope of this line is 2/3.
Subbing this info and the coordinates of one of the points into y = mx + b, we get:
-2 = (2/3)(9) + b. Solving for b: b = -2 -18/3 = -8. Then the equation of this line is:
y = (2/3)x - 8.
Check by subst.: Does (12,0) satisfy this equation? 0 = (2/3)(12) - 8? Yes.
Answer:
<h3>(2, -2)</h3><h3 />
Step-by-step explanation:
As per the graph the intersection point has coordinates:
x = 2, y = - 2
The point is (2, -2)
