distance between one pair of integers that she plotted: 10 unit, 7 unit, 3 unit.
Number line :
the line is a horizontal line that has equally spread number increments. The numbers included on the line will determine how the number on the line can be answered. The question that goes with the number determines how it will be used, for example, in plotting a point.
The numbers on the left are smaller than the numbers on the right of the number line. A number line can also be used to carry out addition, subtraction, and multiplication. We always move right to add, move left to subtract, and skip count to multiply.
Distance formula :
D= right side integer of horizontal line - left side integer of the horizontal line
Distance between the points -8 and 2
d = 2-(-8)
d=10 unit
Distance between the points -5 and 2
d= 2-(-5)
d=2+5
d=7 unit
Distance between the points -5 and -8
d= -5-(-8)
d=-5+8
d=3
