When it says "A dilation with a scale factor of 2 about center (0, 0) has occured" that just means that each coordinate was multiplied by 2 to make the overall figure enlarge.

so for example, if we had a point (3,9) then dilating it with a scale factor of 2 would mean

x = 3 jumps to 3*2 = 6
y = 9 becomes 9*2 = 18


so (3,9) ----> (6,18) after applying the dilation
