Points P, Q, and R are shown on the number line. What is the distance between point P and point R? point p(-2.25) point q(0) point r(2.75)
A.1 unit
b.2.5 unit
c.4.5 unit
d.5 unit
The distance between two points on a number line is found by subtracting the smaller number from the larger number and taking the absolute value. In this case, we subtract -2.25 from 2.75:
2.75 - (-2.25) = 2.75 + 2.25 = 5
Therefore, the distance between point P and point R is 5 units. Answer choice d) 5 unit is the correct option.
To find the distance between points P and R on the number line, we subtract the coordinates of point P from the coordinates of point R.
Point P is at -2.25, and point R is at 2.75.
Distance = |2.75 - (-2.25)| = |2.75 + 2.25| = |5| = 5
Therefore, the distance between point P and point R is 5 units.
The correct answer is d. 5 units.
