Which is an equation of the line containing the points (4, 6) and (6 ,10) in standard form

Find the distance between (0,5) & (-4,2)

How do you write something in scientific notation?

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.
