This is geometry work I need it ASAP can someone please help me

Give all possible names for the line shown.calculation tip: lines can be written with either point first.

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Which number line correctly shows 0.8 + 0.3?
