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

(4,30)

(6,38)

(8,44)

(10,50)

(12,55)

A) y=3.1x+18.6

B) y=0.59x+3.29

C) y=1.13x-14.69

D) y=0.32x-5.89

it is probably the graph on the bottom right.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
