Which equation of the least squares regression line most closely matches the data set?

Note: The variable x represents the years after 1972.

yˆ=15.3x−25.4

yˆ=15.3x+25.4

yˆ=0.06x−28

yˆ=1.03x−56

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

3+3+3+2*2*2+29*12 = 365
