What is the image of point A(3,1) after a dilation with the center at the origin and a scale factor of 4?
Just multiply the coordinates by 4!
To find the image of point A(3,1) after a dilation with the center at the origin and a scale factor of 4, you can multiply each coordinate of point A by the scale factor.
In this case, the scale factor is 4. So, the x-coordinate of the image will be 3 * 4 = 12, and the y-coordinate of the image will be 1 * 4 = 4.
Therefore, the image of point A(3,1) after the dilation is A'(12,4).
