EXERCISE 29.12
Q1.
Solution:
Q2.
Solution:
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).
