This is the coordinate notation to describe a slide 5
units to the left and 1 unit up.
What is (x, y)→(x-5, y+1)?
These are the coordinates of a pentagon with coordinates
A(2,5), B(-1,6), C(-4,2), D(-2,3), and E(1,4) once the pentagon has been reflected
over the y-axis.
What are A’(-2,5), B’(1,6), C’(4,2),
D’(2,3), and E’(-1,4)
This describes what happens to the
coordinates put through the following coordinate
notation: (x, y)→(-x, -y+2)
What is: a reflection about the
y-axis, another reflection about the x-axis, and finally a shift two units up?
Make your wager
Starting with the vertices of a triangle at A(2,3)
B(5,6) and C(-2, 1) these are the coordinates after a reflection about the x-axis then a slide to the right 2 units and up 3
units.
What is A’=(4,0), B’=(7,-3), and
C’=(0,2)?
