Suppose you have a dataset with one independent variable ( $x$ ) and one dependent variable (y). You fit a linear regression model to the data and obtain the following regression line: $Y=2X+1$. Which of the following statements is true? The slope of the line is 1. For every two unit increase in $\mathrm{X}$, there is a one unit increase in $\mathrm{Y}$. For every one unit increase in $X$, there is a two unit increase in $Y$ The $R^{\wedge }2$ value of the model is 2 .
