Gustavo and Yuki were asked to find an explicit formula for the sequence 19.0, -19, -38, ..., where the first term should be h(1). Gustavo said the formula is h(n) = 19 – 19n.
Yuki said the formula is h(n) = –19+ 19n.
Which one of them is right?

well the answer to that is xoxoxo

step-by-step explanation:

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
