Taking the testthe graph below shows the line of best fit for data collected on the depth, in feet, and velocity, in feet per second, at ten points along the columbia river. which of the following is the equation of the line of best fit? y = -0.15x + 0.15 y = -6.67x + 2.1 y = -6.67x + 13 y = -0.15x + 1.95

the f

last graph i believe

step-by-step explanation:

worked it out i believe

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
