Question

A. State the coordinates of each point and in which quadrant they lie.

b. What are the coordinates of point K if it is reflected about the x-axis?
c. What are the coordinates of point L if it is reflected about the y-axis?
d. What are the coordinates of point J if it is reflected about both the x- and y-axis?

Answer 1

a)

• I (1, 2) quadrant 1
• J (3, -1) quadrant 4
• K (-4, 0) x-axis
• L (-4, 2) quadrant 2
• M (4, -4) quadrant 4

b) (-4, 0)

c) (4, 2)

d) (-3, 1)

Explanation:

a)

• I (1, 2) quadrant 1
• J (3, -1) quadrant 4
• K (-4, 0) x-axis
• L (-4, 2) quadrant 2
• M (4, -4) quadrant 4

b) (-4, 0) doesn't move as it is already on the x-axis

c) (4, 2)

d) (-3, 1)

reflected in the x-axis = (3, 1), then reflected in the y-axis = (-3, 1)
