Do you understand dilation already?

Answer 2

i understand dialation but I cant figure this one out.

Answer 3

And also, is there a graph with the lines plotted on it available, or are you expected to make one yourself?

Answer 4

The only one that would make any sense is B because the line does not change position on the x axis, just size

Answer 5

ok thank you!
