Q & A


CBSE Class 9 - Maths - Co-Ordinate Geometry (Questions and Anwers) (#cbseNotes)


Q1: Write the name of the point where both axes intersect?

Answer: Origin


Q2: In which quadrant(s), ordinate of a point is negative?

Answer: III and IV


Q3: If the cooridnates of of two points P(-2,3) and Q(-3, 5), then find (abscissa of P) - (abscissa of Q) 

Answer: = (-2) - (-3) = -2 + 3 = 1



Q4: Plot the points A (-4,4), B (4,4) and C (0,0). Join AB, AC and BC and name the geometrical figure obtained.

Answer: A triangle.
