The equation y=4x represents the number of red skittles (y) for every green skittle (x) in a bag. Therefore, there are red skittles for every 4 green skittles.
A. 4
B. 8
C.12
D. 16

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

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
