Four students from each of the grade levels 4 through 8 at Wilson School were selected at random and surveyed about the number of books they read. The scatterplot above shows the number of complete
independent-reading books, y, that each of the 20 students read during the last school year. A line of bet fit
for the data is also shown and has the equation y = 2x + 4, where x is the grade level of the student.
How many more independent-reading books did Tasha read than the number of books predicted by the
given line of best fit for someone in her grade?

no

step-by-step explanation:

2 pecks

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
