Aset of x and y scores has a regression equation with a slope of b = 4. if the mean for the x values is mx = 2 and the mean for the y values is my = 6, what is the y-intercept value for the regression equation?
-2
-22
4
-4

-2

Step-by-step explanation:

In a linear regression model we have the equation that relates and , where is the estimator of the slope and is the estimator of the Y-intercept. The coefficients and can be estimated with the equations:

. Thus,

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
