The difference of the product of 3 and x and y is 13. The sum of -x and the product of 4 and y is 25. What are the values of x and y?

pi x^2

step-by-step explanation:

pi times x squared

c

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

okay..i will pick 8!
