Well the numbers we know are five, 1,000 and 250
Three collinear points essentially means that you need to find 3 points on the same line. E, B, and the point A seem to do that (or there would be no collinear points in a set of 3)
120 inches because 3 meters is equal to 118.11 and that rounded to the nearest ten equal 120
To find the x-int., let y = 0 and solve for x: 13x = 6, so x = 6/13: (6/13, 0)
To find the y-int., let x =0 and read off the y-int: (0, -6)
