Question
Find the distance with the help of the number line given below.
d(P, J)
Advertisements
Solution
It is known that the distance between the two points is obtained by subtracting the smaller co-ordinate from the larger co-ordinate.
The co-ordinates of points P and J are −4 and −2 respectively.
But −2 > −4
∴ d (P, J) = −2 − (−4)
∴ d (P, J) = −2 + 4
∴ d (P, J) = 2
