You can put this solution on YOUR website! In the Cartesian plane, find the coordinates of the point along the x-axis that is 5 units from the point (2,-3).
**
use distance formula
2 points to work with, (x,0) and (2,-3)
5=√[(x-2)^2+(0-3)^2]
5^2=(x-2)^2+(0-3)^2
25=x^2-4x+4+9
x^2-4x-12=0
(x-6)(x+2)=0
x=6
or
x=-2
