what is the basic method of finding co-ordinates with a given equation

Question

parthkohli · Answer

Find what $\rm x $ is.
Find what $\rm y$ is.

Write the values as $\rm (x,y)$

amriju · Answer

its nt possible to determine by one eqn...

anonymous · Answer

well the basic question is to find the co-ordinates where one line meets another

amriju · Answer

u hav the eqn of two lines...jst solve them simultaneously...u will get the values of x n y...

parthkohli · Answer

Ah! Example:$$\rm y = 2x + 3$$and$$\rm y = 6x + 1$$You want to know where they meet each other.

So, this will happen when the solutions of these equations are equal right?

anonymous · Answer

right

parthkohli · Answer

At that point which we require, $\rm y = 2x + 3 = 6x + 1$. Agree?

anonymous · Answer

so you make them equal each other aha

anonymous · Answer

i cannot believe i forgot that

parthkohli · Answer

Yup! Solve the equation $\rm 2x + 3 = 6x + 1$ to get the $\rm x$-coordinates.

anonymous · Answer

thanks for all the help, everyone helped me alot :)

parthkohli · Answer

And for the $\rm y$-coordinate, just find what $\rm 2x + 3$ equals.

You're welcome!
