Draw projections of a 70mm long line parallel to HP, inclined at 40° to VP, with one end 15mm in front of VP and 30mm above HP.

Since line is parallel to HP, both ends are at same height (30mm above HP)
Draw top view inclined at 40° to XY line, showing true length (70mm)
Front view will be parallel to XY line with length appearing foreshortened
Mark the end point 15mm from XY in both views
Complete projections with proper line conventions
