Which equation of a line contains point (1-1) and is parallel toy = 2x + 5?​
ella [17]

Answer:

Answer is y = 2x - 3

Step-by-step explanation:

• Equation of parallel lines have the same slope. So first two equations are okay.

• For point (1, -1):

{ \rm{y = mx + c}} \\ { \rm{ - 1 = 2 + c}} \\ { \rm{c =  - 3}}

• Equation is y = 2x - 3

The coefficient of determination in a simple linear regression model is 64%. What is the correlation level between the dependent
svet-max [94.6K]

Answer: -0.64

Step-by-step explanation:

We know that the coefficient of determination  in a simple linear regression model is denoted by r^2, which gives the proportion of the variance in the dependent variable that is predictable from the independent variable.

Given, the coefficient of determination in a simple linear regression model is 64%.

i.e.

r^2= 0.64\\\\\Rightarrow\ r=\sqrt{0.64}=\pm 0.64

As there is negative relation between the dependent and independent variables.

Then, the correlation coefficient = -0.64
