Simplify the expression. 6x - 3 -9x - 2 like terms

6x-3-9x-2

6x-9x = -3x

-3-2 = -5

the the equation is: -3x-5

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

can i see a photo of the question so i can you?
