Question

show that the points (a,0), (0,b) and (3a,-2b) are collinear. Also find the equation of the line containing them​

Answer 1

Answer:

Step-by-step explanation:

Equation of line passing through (a,0) and (0,b) is x/a+y/b=1

Now we have to check whether the point (3a,-2b) lies on it

Putting x=3a and y=-2b in the above equation,

3a/a+(-2b/b)=3-2=1

So the point (3a,-2b) lies on the line.

So the points are collinear.

Hope you got it.
