Question

The graph and accompanying table shown here display 12 observations of a pair of variables (x, y).

The variables x and y are positively correlated, with a correlation coefficient of r = 0.96.

What is the slope, b, of the least squares regression line, y = a + bx, for these data? Round your answer to the nearest hundredth.

x 3 6 8 9 9 13 15 18 20 21 23 23
y 9 17 15 15 18 24 29 36 43 39 46 35

Answer 1

Y=mx+b
M=slope
b=(idk, some one else has to answer that)
m=rise over run...leme get a graph up

Answer 2

okay

Answer 3

slope is 1.7

Answer 4

always
best clarkydance

Answer 5

okay nd thanks

Answer 6

...he beat me to it...yeah...its 1.7

Answer 7

thanks to both of yall
