Question

What is the distance between the points (9.0) and (0,5) on the coordinate plane?

Answer 1

( x 1 , y 1 ) = ( 9,0 )

( x 2 , y 2 ) = ( 0, 5 )

Distance between the points:

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

= ( 0 - 9 ) ^2 + ( 5 - 0 )^2

= 81 + 25

= 106

square root both sides, we have:

d = 10 . 296

d = 10. 3 units ( 1 decimal place)
