What is the point-slope equation of a line with slope -3 that contains the point (-8,-4)?

A. y + 4 = -3(x-8)
B. y+ 4 = -3(x+8)
O c. y-4 = -3(x+8)
O D. y-4 = -3(x-8)
SUBW

A

Step-by-step explanation:

A. y + 4 = -3(x-8)

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

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
