Draw a number line and mark on it, if possible, all described points. positive numbers

Step-by-step explanation:

Sorry tried my best

                                                                               All the positive numbers

                                                                          >

   -10   -9   -8   -7   -6   -5   =4   -3   -2   -1   0   1   2   3   4   5   6   7   8   9   10

answer: it is a.,b.,d.

step-by-step explanation:

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
