Question

which of the following would be a line of reflection that would map ABCD onto itself? A(-3,0) B(-3,2) C(-1,2) D(-1,0)

Answer 1

The line of reflection that would map ABCD onto itself is the line y = x + 3

What is a transformation?

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the increase or decrease in the size of a figure.

The equation of the line passing through A(-3, 0) and C(-1, 2) is:

y-0 = [(2-0)/(-1-(-3))](x - (-3)]

y = x + 3

The line of reflection that would map ABCD onto itself is the line passing through AC which is y = x + 3
