Answer: second option.
Step-by-step explanation:
Given the transformation →
You must substitute the x-coordinate of the point A (which is ) and the y-coordinate of the point A (which is
) into
to find the x-coordinate and the y-coordinate of the image of the point A.
Therefore, you get that the image of A(2,-1) is the following:
You can observe that this matches with the second option.
Recall that the slope is the "average rate of change" of any function.
