Apreimage 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?

a.) length = nx, slope = nm
b.) length = nx, slope = m
c.) length = x, slope = m
d.) length = x, slope = nm
e.) length = (n + m)x, slope = nm
