To support a shelf, the diameter of a bolt can be measured anywhere from 0.2 cm less than 1.5 cm to 0.2 greater than 1.5 cm. which graph represents the possible measures of the diameter of the bolt

In the question "To support a shelf, the diameter of a bolt can measure anywhere from 0.2 cm less than 1.5 cm to 0.2 cm greater than 1.5 cm. Which graph represents the possible measures of the diameter of the bolt?" The values from 0.2 cm less than 1.5 cm to 0.2 cm greater than 1.5 cm are values from 1.5 - 0.2 to 1.5 + 0.2 = 1.3 cm to 1.7 cm The graph is a graph on the number line starting from the point 1.3 to 1.7.
