Question

Find the distance between the points 4,7 and -5,7

Answer 1

9

Explanation:

Horizontal line from 4 to -5.

Answer 2

Distance formula is:
`\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }`

`(x_(1),y_(1)) = (4,7)\\(x_(2),y_(2)) = (-5,7)`

Thus let us plug in all the know values and solve:

`√((-5-4)^2+(7-7)^2) =√((-9)^2) =√(81) = 9`

Thus the distance is 9
