question 39

Multiple Choice

Let $\vec { v } _ { 1 } = 2 \vec { i } - 1 \vec { j } + \vec { k }$ and $\vec { v } _ { 2 } = 1 \vec { i } + \vec { j } + \vec { k }$ Find a parametric equation for the plane through the point (1, 2, -1) and containing the vectors $\vec { v } _ { 1 }$ and $\vec { v } _ { 2 }$ Select all that apply.

• A) \(x = 1 + 2 t + 1 s , y = 2 - 1 t + s , z = - 1 + t + s\)
• B) \(x = 1 + 2 t - 1 s , y = 2 - 1 t - s , z = - 1 + t - s\)
• C) \(x = - 1 + 2 t + 1 s , y = - 2 - 1 t + s , z = 1 + t + s\)
• D) \(x = 1 - 2 t + 1 s , y = 2 + 1 t + s , z = - 1 - t + s\)
