Answer 1

Answer:

Step-by-step explanation:

Equation of line passes through the points (3,−4,−5) and (2,−3,1) is given by

2−3

x−3

​

=  

−3+4

y+4

​

=  

1+5

z+5

​

 

⇒  

−1

x−3

​

=  

1

y+4

​

=  

6

z+5

​

=k (say)

⇒ x=3−k,y=k,z=6k−5

Therefore, any point on the line is of the form (3−k,k−4,6k−5)

This point lies on the plane 2x+y+z=7

∴ 2(3−k)+(k−4)+(6k−5)=7

⇒ 5k−3=7⇒k=2

Hence, the coordinates of the required point are (3−2,2−4,6×2−5) i.e,(1,−2,7)
