If x = 2 and y = 6 , evaluate the following expression: 100 − 3 ( 3 y − 4 x )

70

Step-by-step explanation:

100 - 3 ( 3(6) - 4(2) )

100 - 3 (18-8)

100 - 3 (10)

100 - 30= 70

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
