John recorded the weight of his dog Spot at different ages as shown in the scatter plot below.

Part A:
Write an equation that would describe the line of best fit.

Part B:
Using the line of best fit, make a prediction of Spot's weight after 18 months.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

answer:

a=9

step-by-step explanation: lmk if you need a 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
