उत्तर

This statement is True.

Explanation:

We have given line as `(x - 5)/3 = (y + 4)/7 = (z - 6)/2`

By comparing with equation

`(x - x_1)/a = (y - y_1)/b = (z - z_1)/c`

We get given line passes through the point (x1 , x2 , x3 )

i.e., (5, - 4, 6) and direction ratios are (a, b, c)

i.e., (3, 7, –2).

Now, we can write vector equation of the line as `vecr = (5hati - 4hatj + 6hatk) + lambda(3hati + 7hatj - 2hatk)`
