What composite transformations could be used to have triangle 1 turn into triangle 2?
1 answer:
Answer:
see below
Step-by-step explanation:
The vertex order has been reversed, so a reflection is involved. The direction of the short side has been changed by 90°, so a rotation is potentially involved. Depending on the precise rotation and/or reflections, translation may be involved.
One potential set of transformations is ...
- rotate 90° CW about the origin
- translate left 1 and down 3
- reflect across the y-axis
Another potential set of transformations (shown below) is ...
- reflect across the line x+y=1
- translate down 4

Answer:
Step-by-step explanation:
The slope of the line joining the 2 points is a measure of the average rate of change.
Calculate slope m using the slope formula
m =
with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (- 3, - 2)
m = =
=
← average rate of change
