G9-MATH-L3 Coordinate Geometry

What is the primary purpose of coordinate geometry?

• To describe the position of points in a plane
• To calculate the area of shapes
• To solve algebraic equations
• To measure angles

Who is credited with the development of the Cartesian coordinate system?

• Isaac Newton
• René Descartes
• Euclid
• Pythagoras

In the Cartesian coordinate system, what do the coordinates (x, y) represent?

• Distance from the origin
• Position relative to the axes
• Area of a rectangle
• Volume of a cube

What are the coordinates of the origin in the Cartesian plane?

• (1, 1)
• (0, 0)
• (1, 0)
• (0, 1)

If a point is located in the 3rd quadrant, what can be said about its coordinates?

• Both coordinates are positive
• Both coordinates are negative
• The x-coordinate is positive and the y-coordinate is negative
• The x-coordinate is negative and the y-coordinate is positive

How do you determine the x-coordinate of a point in the Cartesian plane?

• By measuring the distance from the x-axis
• By measuring the distance from the y-axis
• By finding the angle with the x-axis
• By counting the grid squares from the origin

What is the x-coordinate of the point P if it is located 4 units to the right of the y-axis?

• -4
• 0
• 4
• 8

Which of the following statements is true regarding the coordinates of a point in the 2nd quadrant?

• The x-coordinate is positive and the y-coordinate is negative
• The x-coordinate is negative and the y-coordinate is positive
• Both coordinates are negative

If a point has coordinates (3, -2), in which quadrant does it lie?

• 1st quadrant
• 2nd quadrant
• 3rd quadrant
• 4th quadrant

What is the relationship between the signs of the coordinates and the quadrants in the Cartesian plane?

• Positive x and y in all quadrants
• Negative x and y in all quadrants
• Positive x and negative y in the 4th quadrant
• Negative x and positive y in the 1st quadrant
