The Rectangular Coordinate System

It is constructed of two real number lines which intersect at a right angle.

• Planar Graph

• Perpendicular Coordinate System

• Descartes's Plane

• Rectangular Coordinate System

Who is the French mathematician credited with developing the Cartesian plane?

• Galileo Galilei

• Blaise Pascal

• René Descartes

• Pythagoras

TRUE or FALSE

In the rectangular coordinate system, the horizontal number line is known as the x-axis, while the vertical number line is termed as the y-coordinate.

• TRUE

• FALSE

Answer explanation

This statement is FALSE.

The horizontal number line is known as the x-axis, while the vertical number line is called the y-axis.

MORSE TYPE

Statement A: The x- and y-axes divide the plane into four regions called sections.

Statement B: These regions are named using roman numerals I, II, III, and IV.

• BOTH statements are TRUE.

• Statement A is FALSE, while Statement B is TRUE.

• BOTH statements are FALSE.

• Statement A is TRUE, while Statement B is FALSE.

Answer explanation

The plane is divided into four quadrants by the x- and y-axes.

In which quadrant is the point with coordinates (-5,30)?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

PLEASE TYPE YOUR ANSWER IN ALL CAPITAL LETTERS ONLY

The intersection of the two axes is known as the (a)   , which corresponds to the point (0,0).

What is the name of the first and second number in an ordered pair?
