(-3,4)(-6,-1)
The easy way
look at the y's = 4 and -1 the difference is 5 now /2 = 2.5
so the y midpoint is 2.5 from each point or 1.5
look at the x's = -3 and -6 the differebce is 3 now /2 = 1.5
so its 1.5 from each point or -4.5
so midpoint is (-4.5, 1.5) or (-9/2, 3/2) or C
the formula way:
for x
x1+x2/2
-3+-6/2
-9/2 (which is -4.5)
for y
y1+y2/2
4+-1/2
3/2 (which is 1.5)
Change 3 to 6 and 2 to 4
Now Do
3/6 + 5/6 = ?
? = 8/6
8/6 = 1 2/6
1 2/6 = 1 1/3

Answer:
George made the first mistake by multiplying by 7 instead of 8
Step-by-step explanation:
The total cars needed to have a mean of 24:
24 x 8 = 192
Total cars sold during the seven months:
18 + 22 + 26 + 12 + 25 + 20 + 19 = 142
Subtract the total cars sold from the total cars needed:
192 - 142 = 50
George needs to sell 50 cars in the eight month in order to have an average of 24 cars sold per month.
