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

A dilation has the effect of stretching or shrinking the line segment by the factor of n. So the length of the new image would be nx and the slope is m.
