Answer 1

Answer:

1. on y axis below units

2.y coordinate is zero

3.5 units

4.a=0 b = -2

5.P(0,-6)

6.(0,-4)

7. i) Q(4,0)

ii) length of PQ = 5 UNITS

iii) 4 units

Answer 2

Step-by-step explanation:

2) distance from the origin is 3units.

3) y-co ordinate becomes "ZERO".

4) perpendicular distance from y-axis is 5 units

5) a=0 & b=-2.

6) co-ordinates are (0,-6).

7) (0,-4)

8) i) Q (4,0)

ii) 5units

iii) 4units

9) (2,3) in 1st Quadrant

(5,-6) in 4th "

(2,0) in 1st "

(-5,2) in 2nd "

10) 1 is the answer
