Answer:
B
Step-by-step explanation:
The solution to a system of equations is where the two lines intersect at the exact same (x,y).
On the graph below, the point of intersection is between x values -6 & -7 and between y values -3 & -4. The best estimate would be half way between each of these values.
(-6.5, -3.5)
Answer:
(1/2, -1)
Step-by-step explanation:
The midpoint is the average of the end points:
M = (R + S)/2 = ((4, -7) + (-3, 5))/2 = ((4-3)/2, (-7+5)/2) = (1/2, -2/2)
M = (1/2, -1)
10000 millions or 999 billion is 1 trillion
