Q3 of 7 Page 211

Express y in terms of x given that 2x–5y = 7. Check whether the point (–3 –2) is on the given line.

The given equation is 2x–5y = 7


5y = 2x – 7



The above equation in terms of x is


Checking the point (–3, –2) for the line



–10 = 13


∷ LHS ≠ RHS


∴ (–3, –2) is not on given line.
