If the question is only asking for the difference between the y in the two points, then the difference can be simply calculated as y2 - y1 as follows: <span>∆y = y2 - y2 = 10-(-5) = 15 units
If the two given points are to be used to determine the slope of a line, then the slope can be calculated as follows: slope = (y2-y1) / (x2-x1) = (10--5) / (0--3) = 15/3 = 5</span>
Since there is three feet in a yard you multiple 450 by 3 which equals 1350 then you multiple that by two because you multiplying the time by 2 which equals 2700.
208° is a 3rd-quadrant angle, so its x-coordinate will be negative. Your calculator can tell you that 5 times the cosine of this angle is -4.41, or you can refer to a diagram.
