<span>A line segment has (x1, y1)as one endpoint and (xm, ym)as its midpoint.
Use the formula? (x2, y2) = (2xm − x1, 2ym − y1)
to find the coordinates of the endpoint of a line segment if the coordinates of the other endpoint and midpoint are (1, 8), (−3, −1) and (−7, 16), (3, 6),respectively.
So you first do 26 x 14 = 364 miles for 14 gallons 838 ÷ 364 = 2.302 You then have to round the number, and because you can't stop 0.302 times, the answer is 3. ... I think, someone might need to double check me
