Line L is mapped into m by a dilation centered at the origin with a scale factor of 4/5 , Line m is represented by y=3×+8 and it passes through the point whose coordinates are (-4,4). which of the following is true about line 1 ?

Here , we want to select which of the options correctly depicts what is true of line l.
The best way to go about this is finding the equation for line m.
