the line joining the points 2, -3,1 and 1,2,-4 cuts the plane 2x+3y-5z+3 = 0 at (a,b,c) then the value of a is
Answers
Step-by-step explanation:
Given:
The line joining the points 2,-3,1 and (1,2,-4) cuts the plane 2X+3y-5z+3=0 at (a,b,c).
To find: Value of a
Solution:
Formula to find equation of line passing through two given points A(x1,y1,z1) and B(x2,y2,z2)
Here points are
A(2,-3,1), B(1,2,-4)
Let (x,y,z) are the points where line cuts the plane
these must satisfy equation of plane
put these into plane
Put value of k in coordinates of point of intersection.
Coordinates of intersection of plane are
69/38,79/38,3/38
ATQ,these are (a,b,c)
Value of a is 69/38
Final answer:
Value of a is 69/38
Hope it helps you.
