The graph shows the solutions to the inequalities y>- 1/3 x+5 and y< - 1/3x -1 A. there is a solution, and it is shown by region c.

B. there is a solution and it is shown by region a.

C. there is a solution and it shown by region b.

D. there is no solution.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
