Answer:

Step-by-step explanation:
Given

Transformation = Rx-axis
Required
Determine the image
When rule Rx-axis is applied to a point (x,y),
The new coordinate point is (x,-y)
<em>In other words, the y coordinate is negated</em>
So, when rule Rx-axis is applied to

The image of the point is


BDC is adjacent (Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.)
Aimme is right. All the sides are obtuse. They do not equal exactly 90 degrees.
Answer:
Find the function of two points first. Then check whether the third point is on it
