Question

The equation of the line joining the points $(-3,4,11)$ and $(1,-2,7)$ is

• A. $\frac{x+3}{2}=\frac{y-4}{3}=\frac{z-11}{4}$
• B. $\frac{x+3}{-2}=\frac{y-4}{3}=\frac{z-11}{2}$
• C. $\frac{x+3}{-2}=\frac{y+4}{3}=\frac{z+11}{4}$
• D. $\frac{x+3}{2}=\frac{y+4}{-3}=\frac{z+11}{2}$

Answer 1

Answer: (B)

$\frac{x+3}{-2}=\frac{y-4}{3}=\frac{z-11}{2}$

Answer 2

$A (-3,4,11) B (1,-2,7)$ Dr's of $AB$ $( a , b , c )=1-(-3),(-2,-4) 7,-11$ $4,-6,-4$ $=-2,3,2$
