timama [110]

Reasoning Criticism Lisa modeled 2 with a number line (3). Her logical number line is -6.

<h3>What is meant by number line?</h3>
  • A number line is a graphical representation of numbers on a straight line. A number line has numbers that are sequentially placed at equal distances along its length.
  • It can be extended in any direction indefinitely and is usually represented horizontally. A number line is a horizontal line with mathematical increments spaced evenly.
  • The numbers on the line will determine how to answer the number on the line. The number's use is determined by the question that goes with it, such as plotting a point.
  • The number line is a straight line with divisions at equal intervals, similar to a scale.

Therefore, Reasoning Criticism Lisa modeled 2 with a number line (3). Her logical number line is -6.
