Question

These are the values in Greta’s data set. (2, 43), (3, 46), (4,61), (6, 70), (7,74) Greta determined the equation of a linear regression line, and determined that these are the predicted values. (2, 43), (3, 50), (4,56), (6, 69), (7,76) Use the point tool to graph the residual plot for the data set.

Answer 1

Okay, i'm pretty sure that if you make a residual plot its a plot using all those points labeled. So plot those points on a graph, if you are using a K12 diagram use the 1-10 as 100-1000 (basically add a zero to every number) 

Answer 2

The equation of a linear regression line is y = 6.2x + 30.6 and all the points are on the line.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more two variables.

These are the values in Greta’s data set. (2, 43), (3, 46), (4,61), (6, 70), and (7,74). Greta determined the equation of a linear regression line.

$\rm (y - 43) = \dfrac{74-43}{7-2} (x-2)\\\\y = 6.2x+ 30.6$

These are the predicted values. (2, 43), (3, 50), (4,56), (6, 69), and (7,76).

Then the graph is a straight line. All the points are on the line.
