The answer to the velocity question if anyone needs it! Part A:

The equation in standard form would be 2x+y=22.

Using two points: (4,14) and (9,4) you can solve for the slope 10/-5=-2

Then using y-y1=m(x-x1) (point-slope form) to identify one point on the line.

So for the equation, it would be y-4=-2(x-9) add 2x to both sides of the equation then you would add 4 to both sides.

Then you are left with 2x+y=22

Part B:

To graph the equation for the first 10 hours you would substitute 10 for x because x is the time variable.

answer: the answer is fre sha voca do

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
