Which of the following is the slope of the line with the equation begin equation . . negative 7 times x equals . . 6 plus 3 times y . . end equation? a –negative seven over three b –negative three over seven c three over seven d seven over three

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
