Suppose that the sample regression equation of a model is $= 4 + 1.5 x _ { 1 } + 2 x _ { 2 } - x _ { 1 } x _ { 2 }$ . If we examine the relationship between $x _ { 1 }$ and y for four different values of $x _ { 2 }$ , we observe that the four equations produced differ only in the intercept term.

The Answer of Suppose that the sample regression equation of a model is $= 4 + 1.5 x _ { 1 } + 2 x _ { 2 } - x _ { 1 } x _ { 2 }$ . If we examine the relationship between $x _ { 1 }$ and y for four different values of $x _ { 2 }$ , we observe that the four equations produced differ only in the intercept term.

Suppose That the Sample Regression Equation of a Model Is =4+1.5x1+2x2−x1x2= 4 + 1.5 x _ { 1 } + 2 x _ { 2 } - x _ { 1 } x _ { 2 }=4+1.5x1​+2x2​−x1​x2​
