Presuming you are asking for the distance between the two points use the distance formula derived from Pythagoras theorem

Explanation:

Distance = sqrt (("x2" - "x1")^2 + ("y2" - "y1")^2√(x2−x1)2+(y2−y1)2

Now, we just have to substitute the values in for the variables:

Distance = sqrt (("x2" - "x1")^2 + ("y2" - "y1")^2√(x2−x1)2+(y2−y1)2
= sqrt (("-1" - "1")^2 + ("5" - "-4")^2√(-1−1)2+(5−-4)2
= sqrt ((-2)^2 + (9)^2√(−2)2+(9)2
= sqrt ((4 + 81)√(4+81)
= sqrt (85)√85
approx 9.22≈9.22

therefore The distance between A and B is 9.22 units

All the best!
