Under a dilation of a scale factor 3 centered at the origin, ab becomes a’b’. determine the coordinates of a’b’ and sketch a’b’ on the graph

answer: add the !

step-by-step explanation: then we will answer

the first one, all those points on the line just make a strait line.

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

answer: graph 2
