Question

For x = -3, y = -2, u = -9, v = 13 the point (x+y, u+v) lies in which quadrant? (2 mark)

Answer 1

Abscissa is x + y = -3 +(-2) = -5

Ordinate is u + v = -9 + 13 = 4 (1 mark)

The point is (-5, 4).

Since the x - coordinate is negative and y - coordinate is positive the point lies in II quadrant.
