Rose drew a regression line for this paired data set. her line passed through (1, 2) and (3, 5) . what is the equation of rose's regression line?

A.

Step-by-step explanation:

We are given that,

The linear regression passes through the points (1,2) and (3,5).

As, the slope of a linear line is given by, .

We get, the slope of the linear regression is,

Slope = .

i.e. Slope = .

i.e. Slope = .

i.e. Slope = 1.5

As, the linear line is given by 'y=mx+b', where m is the slope and b is the y-intercept.

Substituting the slope and point (1,2) in the general form, we have,

implies implies i.e. b= 0.5

Hence, the equation for the regression line is

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
