Any point on the line AB is the form:

– r + 3, r – 4, 6r – 5


Let p be the point of intersection of the line AB and the plane 2x + y + z = 7

Thus, we have,

2(– r + 3) + r – 4 + 6r – 5 = 7

– 2r + 6 + r – 4 + 6r – 5 = 7

5r = 10

r = 2


Now substitute the value of r in – r + 3, r – 4, 6r – 5, the coordinates of P are:

(– 2 + 3, 2 – 4, 12 – 5) = (1, – 2, 7).
