Damian dilates △PQR shown on the coordinate grid with a scale factor of 0.5 centered at the origin. Then he translates the image 1 unit up and 3 units to the right to form △P'Q'R'. What are the coordinates of the vertices of △P'Q'R'?

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
