Select the correct equation of a line that contains the following: slope = -1,
passes through the point (1,-7).
y = -x - 6
y = -x + 8
y = -x + 6
y = X-8

answer: asdfghjkl,mnbv

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
