## Coordinate GeometryQ & A

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

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

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.

Q5: The abscissa and ordinate of a point are –3 and –5 respectively then write down the ordered pair.
