Find the distance between the points: (–6, 7) and (–1, –5). In your final answer, include the formula and calculations that you
expeople1 [14]

Answer: The distance between the points (-6,7) and (-1,-5) is 13 units.

Solution:

P1=(-6,7)=(x1,y1)→x1=-6, y1=7

P2=(-1,-5)=(x2,y2)→x2=-1,y2=-5

Distance between points P1 and P2: d=?

d=sqrt [ (x2-x1)^2 + (y2-y1)^2 ]

Replacing the knwon values:

d=sqrt [ (-1-(-6))^2 + (-5-7)^2 ]

d=sqrt [ (-1+6)^2 + (-12)^2 ]

d=sqrt [ (5)^2 + 144 ]

d=sqrt [ 25 + 144 ]

d=sqrt [ 169 ]

d=13

Calculate the distance between A(4,3) and B(-1, 6)
elixir [45]

Answer:

Step-by-step explanation:

The formula for determining the distance between two points on a straight line is expressed as

Distance = √(x2 - x1)² + (y2 - y1)²

Where

x2 represents final value of x on the horizontal axis

x1 represents initial value of x on the horizontal axis.

y2 represents final value of y on the vertical axis.

y1 represents initial value of y on the vertical axis.

From the given information,

x2 = - 1

x1 = 4

y2 = 6

y1 = 3

Therefore,

Distance = √(- 1 - 4)² + (6 - 3)²

Distance = √(- 5² + 3²) = √(25 + 9) = √34

Distance = 5.83
