Question

Find the distance between the points (1,5) and (1, -4)​

Answer 1

Answer:

The distance = 9 units

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (1, 5) and (1, -4). Substitute:

$d=\sqrt{(1-1)^2+(-4-5)^2}=\sqrt{0^2+(-9)^2}=\sqrt{81}=9$

Answer 2

Answer:

d = 9  

Step-by-step explanation:

The joining the two points is shown in the graph below.

The distance from (1, 5) to (1, -4) is

d = 5 – (-4)  

  = 5 + 4  

  = 9
