. Jumbo bought 5 books, each with a whole-number price.
Trava [24]

Mean is average. Multiply total books by the mean to find the total cost:

5x 10 = $50 total.

Subtract the highest and lowest prices to find the total of the remaining 3 books.

50 - 15-6 = 29

The median price was 8, this is the middle number, subtract 8 from 29 to get the cost of the last 2 books:

29-8 =21

Now you need a price lower than the median but higher than the lowest cost so that has to be 7

Subtract 7 from 21 to get the cost of the last book 21-7 = 14

The price of the remaining books is $7 and $14

y-y1=m(x-x1)

the slope of paralell lines ar the same

y=3x+2
y=mx+b
m=slope
m=3

a point is (-2,0)
slope is 3

y-0=3(x-(-2))
y=3(x+2)
y=3x+6
the equation is y=3x+6
