Question

Find the distance between the pair of points (2,6) and (7,-4)​

Answer 1

5

Explanation:

Lets use the distance between points formula:

`\sqrt[]{(x1-x2)+(y1-y2)^2}`

x1=2

x2=6

y1=7

y2=-4

`√((2-6)^2+(7-4)^2)`

`√((4)^2+(3)^2)`

`√(16+9)`

`√(25)`=5

5 is the distance between the two points

Answer 2

The distance is 5sqrt5 units

Explanation:

Use distance formula: sqrt((7-2)^2+(-4-6)^2)

sqrt((5)^2+(-10)^2)

sqrt(25+100)

sqrt(125)

5sqrt5

So the answer is 5sqrt5 units
