Question

The scatter plot and table show the number of grapes and blueberries in 10 fruit baskets. When you use the two data points closest to the line, which is the equation of the regression line?

Answer 1

Is there a graph?

Answer 2

oh, ok

Answer 3

I think its the first one A

Answer 4

Slope = y2-y1/x2-x1

(20-12)/(52-28) is approximately 1/3.. That leaves options C or D

Now use the point slope form. Use the point (20,8)
y-y1=m(x-x1) m is the slope
y-8=1/3(x-20) (plug in)
y-8 = 1/3x - 20/3 (distribute)
y= 1/3x + 4/3 (add 8)

Answer 5

and yes A :)

Answer 6

okay possitively
