`bar(JK)` is dilated by a scale factor of n with the origin as the center of dilation, resulting in the image `bar(J'K')`. The slope of `bar(JK)` is m. If the length of `bar(JK)` is l, what is the length of `bar(J'K')`? A. m × n × l B. (m + n) × l C. m × l D. n × l

old question but will answer so this can be closed

when you scale some length (x) by some scale factor (y), simply multiply x * y to get the new length
