Which is the best CONTEXTUAL description of the y-intercept for the linear regression equation of the rats:Weight = 100 + 40(Time)?
|
|
The y-intercept is 100, which means the rat is predicted to weigh 100 grams at birth.
|
|
|
The y-intercept is 100, which is where the graph crosses the y-axis.
|
|
|
100 is where the data starts on the y-axis.
|
|
|
The y-intercept is 100, which means at a weight of 0, the rat will take 100 seconds.

Explanation:
Detailed explanation-1: -Which is the best CONTEXTUAL description of the y-intercept for the linear regression equation of the rats: Weight = 100 + 40(Time)? The y-intercept is 100, which means the rat is predicted to weigh 100 grams at birth. The y-intercept is 100, which is where the graph crosses the y-axis.
Detailed explanation-2: -The symbol a represents the Y intercept, that is, the value that Y takes when X is zero. The symbol b describes the slope of a line.
