The Answer of For the following regression equation $\tilde { y } = 75 + 20 x _ { 1 } - 15 x _ { 2 } + 5 x _ { 1 } x _ { 2 }$ ,a unit increase in x₂,while holding x₁ constant at 1,changes the value of y on average by: A) -5 B) +5 C) 10 D) -10

For the Following Regression Equation y~=75+20x1−15x2+5x1x2\tilde { y } = 75 + 20 x _ { 1 } - 15 x _ { 2 } + 5 x _ { 1 } x _ { 2 }y~​=75+20x1​−15x2​+5x1​x2​

For the Following Regression Equation $\tilde { y } = 75 + 20 x _ { 1 } - 15 x _ { 2 } + 5 x _ { 1 } x _ { 2 }$
