EXERCISE 29.12

Q1.

Solution:

Q2.

Solution:

Any point on the line AB is the form:

â€“ r + 3, r â€“ 4, 6r â€“ 5

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

Thus, we have,

2(â€“ r + 3) + r â€“ 4 + 6r â€“ 5 = 7

â€“ 2r + 6 + r â€“ 4 + 6r â€“ 5 = 7

5r = 10

r = 2

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

(â€“ 2 + 3, 2 â€“ 4, 12 â€“ 5) = (1, â€“ 2, 7).
