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)

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