what are the new coordinates?

Question

Points M (1,8), K (4,2), and L (-3,5)

If this polygon was translated down 6 units and right 4 units, what are the new coordinates of L'?

If the original polygon was reflected across the x-axis, what are the new coordinates of K'?

If the original polygon was rotated 90° counter-clockwise, what are the new coordinates of M'?

If the original polygon was rotated 180°, what are the new coordinates of K'?

If the original polygon was translated down 5 units and reflected across the y-axis, what are the new coordinates of L'?

Answer 1

Points M (1,8), K (4,2), and L (-3,5)

If this polygon was translated down 6 units and right 4 units, what are the new coordinates of L'?-c

Add 4 to each x-coordinate, subtract 6 from each y-coordinate

If the original polygon was reflected across the x-axis, what are the new coordinates of K'?

Change each y-coordinate to the opposite

If the original polygon was rotated 90° counter-clockwise, what are the new coordinates of M'?

x-coordinate becomes opposite of the y-coordinate.

y-coordinate becomes the x coordinate

If the original polygon was rotated 180°, what are the new coordinates of K'?

x-coordinate becomes its opposite

y-coordinate becomes its

If the original polygon was translated down 5 units and reflected across the y-axis, what are the new coordinates of L'?

Subtract 5 from all y-coordinates

x-coordinate become its opposite

All of these rules are in your text book. Look for them, use them.
