help?!
Polygon MNOPQ is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image M′N′O′P′Q′. The coordinates of point M are (2, 4), and the coordinates of point N are (3, 5).

what is the slope of M'N' ?

i got 1 is that correct?

Yes, slope=1 is correct.
Recall that a dilation will preserve slopes and lines remain parallel.
So slope of the preimage will be the same as the image (in a dilation).
Well done!
