A preimage includes a line segment of length x and slope m. If the preimage is dilated by a scale factor of n, what are the length and slope of the corresponding line segment in the image

length is scaled by n, slope is unchanged.

A preimage includes a line segment of length x and slope m. If the preimage is dilated by a scale factor of n, what are the length and slope of the corresponding line segment in the image?
length = nx, slope = nm
length = nx, slope = m
length = x, slope = m
length = x, slope = nm
length = (n + m)x, slope = nm 
length = nx, slope = nm
