Question

find the condition for the points (a,0) (h,k) and ( o,b)
​

Answer 1

Step-by-step explanation:

Any point lying on the line joining (h,3,−4) and (0,−7,10) can be written in the form of (h−hl,3−10l,−4+14l).

Since, (1,k,3) is also a point on this line, it should satisfy this form.

⇒−4+14l=3.

∴l=

⇒k=3−10l=−2

⇒h(1−l)=1

∴h=2

Hence, h+k=2−2=0
