Find the equation of theplane through the points `(23,1)a n d(4,-5,3)`and parallel to the x-axis. |
Answer» Plane passes through the points `(2, 3, 1) and (4, -5, 3)` Therefore, plane is parallel to vector `" "(4-2)hati+(-5-3)hatj+ (3-1)hatk=2hati-8hatj+2hatk` Also plane is parallel to the x-axis, so it parallel to vector `hati` `therefore` Normal to the plane = `|{:(hati,,hatj,,hatk),(2,,-8,,2),(1,,0,,0):}|=2hatj+8hatk` Hence, equation of plane through point (2, 3, 1) and normal to vector `2hatj+8hatk` is `" "0(x-2)+2(y-3)+8(z-1)=0` or `" "y+4z-7=0` |
