Question

What is the distance between the points (-5, 9) and (4, 9) on the coordinate plane? 9 9 1 1 10 10 90

Answer 1

9 units

Explanation:

Given: Two points on a coordinate plane are
`(-5,9),\,(4,9)`

To find: distance between points
`(-5,9),\,(4,9)`

Solution:

According to the distance formula,

Distance between points
`(a,b)` and
`(c,d)` is equal to
`√((c-a)^2+(d-b)^2)`

Take
`(a,b)=(-5,9),\,(c,d)=(4,9)`

Therefore,

Distance between points
`(-5,9),\,(4,9)`
`=√((4+5)^2+(9-9)^2)`

`=√((9)^2)`

`=9` units
