Which of the following statements are true about the function y = 3 x ? The function is a direct variation. The function goes through the origin. The constant of variation is . y is 6, when x is 2. I and II I and IV I, II, III, and IV I, II, and IV

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
