Which equation of the least squares regression line most closely matches the data set? x y
2 100
4 83
6 50
8 35
10 23
yˆ=−0.31x+37.3
yˆ=−2.3x+97.9
yˆ=−10.1x+118.8
yˆ=−0.09x+11.5

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
