which one 1,2,3, or 4? ? is the answer? ?

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

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

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
