Question

Express y in terms of x given that 3x-5y=18.check weather the point (1,2) lies on the given line

Answer 1

➡HERE IS YOUR ANSWER⬇

Here, 3x - 5y = 18 .....(i)

or, 5y = 3x - 18

or, y = (3/5)*x - 18/5, which is the required expression.

We satisfy LHS of (i) by the point (1, 2). Then

3.1 - 5.2 = 3 - 10 = -7, not equals to 18.

So, the point (1, 2) doesn't lie on the given line.
