Answer:
- <u>B. a line parallel to </u><u><em>m</em></u>
Explanation:
Imagine two points S with coordinates (a,b) and T with coordinates (c,d) on the line <em>m.</em>
- The slope of the line <em>m</em> is (d - b) / (c -a)
<em />
For your convenience choose the point P as the center of your coordinate system.
Then, when you <em>dilate</em> the line <em>m</em> by a factor K, the images of the points S and T, S' and T', will have coordinates (K × a, K × b) and (K × c, K × d), respectively.
Thus, the slope of the image of the line <em>m,</em> to which the segment S'T' belong, is:
- {K × d - K × b] / [K × c - K × a] = [ K (d-b) ] / [ K (c - a) ] = (d - b) / (c - a)
Hence, the slope of the line <em>m</em> and its image are equal,which means that they are parallel.
