ANSWER
The coordinates of the image are (2,2)
EXPLANATION
The mapping for a reflection across the line y=k is :
We want to find the image of the point (2,-4) after a reflection in the line y=-1.
In this case k=-1.
This simplifies to,
Hence the image is (2,2)
Answer:
A
Step-by-step explanation:
First, put this equation in slope intercept form.
Where m is the slope and b is the y intercept.
Since it's greater than, the solution set is above the line, effectively eliminating graph D.
Now we should graph it.
We can see that the point is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.
