Adelle solved the equation ½ (x + 8) = - 30 as shown. Fill in the correct justification for each step.

Step Justification
1/2(x+8)=-30 Given
x/2+4= -30 blank
x/2= -34 blank
x=-68 blank

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
