The Answer of In the first-order model 
$= 50 + 25 x _ { 1 } - 10 x _ { 2 } - 6 x _ { 1 } x _ { 2 }$ , a unit increase in $x _ { 2 }$ , while holding $x _ { 1 }$ constant at a value of 3, decreases the value of $y$ on average by 3 units.

In the First-Order Model =50+25x1−10x2−6x1x2= 50 + 25 x _ { 1 } - 10 x _ { 2 } - 6 x _ { 1 } x _ { 2 }=50+25x1​−10x2​−6x1​x2​

In the First-Order Model $= 50 + 25 x _ { 1 } - 10 x _ { 2 } - 6 x _ { 1 } x _ { 2 }$
