Consider triangle ABC in the coordinate plane. Dilate triangle ABC from the origin by a scale factor of 2. What is the coordinate of B’?

Multiple Select

Line m is represented by the equation 12x -6y = 24. Determine the equation of line t, the image of line w, after a dilation of scale factor 0.5 centered at point (2, 1). Select all that apply.

• 12x - 6y =24

• y = 2x - 1.5

• y = 2x - 3

• 12x - 6y = 12
