John is 70 years younger than Sharon. Sharon is 4 times as old as John. If you let s= Sharon's age and j= John's age, then the problem can be represented by a system of equations. Which of the following shows a graph of this system and the solution to this problem?

757764

step-by-step explanation:

de77737dd

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
