Given:dot is taller than dab but shorter than dee, and Dave is taller than don. Prove: E is the last letter of the name of the tallest person

- (2, -7)

- lines r and s and lines t and u must be parallel

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
