Question

5. The point of intersection of the line joining the points (3, 4, 1) and (5, 1, 6) and the xy-plane is
​

Answer 1

Answer:

1 is the only meeting point

Answer 2

Answer:

Step-by-step explanation:

First find the equation of this line.

So equation of this line => $\frac{x-x1}{a} =\frac{y-y1}{b} =\frac{z-z1}{c}$

we need a,b,c

a= 5-3 =2, b=1-4 =-3, c=6-1=5

Then the line =>

$\frac{x-3}{2} =\frac{y-4}{-3} =\frac{z-1}{5}$$= p$

Now when the line intersect xy plane, z=0

So p= -1/5

So x = -2+15/5 =13/5

y =23/5
