Answer: X = 3t, Y =2 - t, Z =2
Step-by-step explanation: the plane 
x + y + z =4has normal vector 
M =<1,1,1> and the line 
x = 1 + t, y = 2 − t, z = 2t has direction 
v =<1, −1, 2>. So the vector
A= n × v
=<1, 1, 1> × <1, −1, 2>
=<2−(−1),1−2,−1−1>
=<3,−1,−2>
 
        
             
        
        
        
The area of the triangle is 49 in2, so she can create only 2 triangles.
