Question

Find the distance between the two points in simplest radical form (-6,8) and (-1,-4)

Answer 1

13

Explanation:

d) = √(-1 - -6)2 + (-4 - 8)2

= √(5)2 + (-12)2

= √169

= 13

Answer 2

13

Explanation:

We use the distance formula to find the distance between two points

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

Where ( x1,y1) and ( x2,y2) are the two points

d = sqrt( ( -1 - -6) ^2 + ( -4 - 8) ^2)

= sqrt ( ( -1+6) ^2 + ( -12) ^2)

= sqrt( 5^2 + 144)

= sqrt ( 25+ 144)

= sqrt ( 169)

= 13
