Answer 2

Step-by-step explanation:

Distance between two given points (x1,y1) and (x2,y2) is:

Sqrt[(x2−x1)2+(y2−y1)2]

= d(distance)

Substituting the given values , we have:

5=sqrt[(−2−x)2+(4−y)2]

Square both sides and substitute values for x and y to frame the relation

25 = (-2-x)2+(4−y)2

For example x=-2 and y =-1 would yield in satisfying this equation

Hence , (-2,-1) is one pair of co-ordinates on the x-y axis that satisfies the given equation.
