What is the image of (10,-4)(10,−4) after a dilation by a scale factor of \frac{1}{2} 2 1 centered at the origin?

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
