PLOTTING A POINT IN THE PLANE IF ITS COORDINATES ARE GIVEN

Problem 1 :

Let's label the axes, quadrants, and signs on the following grid :

The x - axis is the _____ axis.

The y - axis is the _____ axis.

Another name for the point (0, 0) is the  _____.

Solution :

The x - axis is the horizontal axis.

The y - axis is the vertical axis.

Another name for the point (0, 0) is the origin.

Problem 2 :

Using the grid below, let's plot the following points and label them with the letter :

Solution :

Problem 3 :

Give the quadrant each set of coordinates lies in :

a) (1, 5) b) (-2, 4) c) (-3, 2) d) (4, -4)

Solution :

a) (1, 5) lies in 1^st quadrant

b) (-2, 4) lies in 2^nd quadrant

c) (-3, 2) lies in 2^nd quadrant

d) (4, -4) lies in 4^th quadrant

Problem 4 :

Give the quadrant that the following points lie in :

Solution :

a) (2, -7) lies in 4^th quadrant

b) (-6 -5) lies in 3^rd quadrant

c) (2, 5)  lies in 1^st quadrant

d) (1, 4)  lies in 1^st quadrant

e) (-3, 2)  lies in 2^nd quadrant

f) (10, -15) lies in 4^th quadrant

Problem 5 :

Graph each point on a coordinate plane. Label the points A - D.

A. (2, 5) B. (0, 4) C. (-1, 2) D) (2, -3)

Solution :
