Answer: For a translation, you need a distance and a direction.
For a rotation, you need a point that is the center of the rotation and the degree (and sometimes direction) of rotation.
For reflection you need the axis or a defined line that the triangle is reflected across.
Step-by-step explanation:
The answer is x-1, hope that helps
Answer:
1. (-3,2) and (-1,2)
Step-by-step explanation:
Reflection over x axis results in change y-coordinates to opposite sign and x-coordinates remain as is
<u>So the coordinates become:</u>
- A(-3, -2) → A'(-3, 2)
- B(-1, -2) → B'(-1, 2)
Correct option is the first one
9^2 = 4.5^2+b^2
81=20.25+b^2
60.75=b^2
b (altitude) = approx. 7.8
-1 is the slope of the line.
