Help me in my approach what im thinking as i need to find x and y

  1. i use slope intercept in point b and c to find the equation then
    2.after getting the equation i use slope intercept a and b . So that i can find x, y as a b and c all have the same line equation

  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:

  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

and then find the coordinates of the third points by using it and b and the equation i have

#

Can i also do it using area of triangle i am not getting that approach

sharp jacinth
#

Oh, you can do it in the following way: find the area of a triangle formed by these three points. If it's equal to 0, then they lie on the same line.

we need to find x and y

sharp jacinth
#

I get that.
Well, the first approach is still probably the easiest.

ik but since i am in 10th grade and the first method isnt taught in schools or books maybe my exam checker wont accept it

sharp jacinth
#

Really? That's very odd.

#

That is probably the first idea you should have in this case.

yh i did by that only

#

but u know typical schools dont accept if i solve a problem with a higher standard solution

Really?
