Q2 of 39 Page 109

Suppose you are given a coordinate system. Determine the quadrant in which the following points lie:

(i) A (4,5) (ii) B (−4,−5) (iii) C (4,−5).

A. Since both X coordinate and Y coordinate are Positive


⇒ (+,+) which is in the first coordinate


B. Since both X coordinate and Y coordinate are Negative


⇒ (-, -) which is in the third coordinate


C. Since both X coordinate is POSITIVE and Y coordinate is Negative


⇒ (+, -) which is in fourth coordinate

Suppose P is a point with coordinates (−8,3) with respect to a coordinate system X’OX ↔ Y’OY. Let X1’O1X1↔ Y1’O1Y1 be another system with X’OX ║X1’O1X1 and suppose O1 has coordinates (9,5) with respect to X ’OX ↔ Y ’OY. What are the coordinates of P in the system X1’O1X1↔ Y1 ’O1Y1?
