4/7-6/7= also -3 4/7-(-1 1/7=

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

the answer is 3/2 and for decimal: 1.5

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
