Hi there! I'd love to help you out.
In geometry, the distance formula is:
√(x2-x1)2+(y2-y1)2
Now we can just plug in the x and y values:
√(-1-8)2+(8-(-4)2
√(-1-8)2+(8+4)2
√(-9)2+(12)2
√(81+144)
√(225)
15
So our distance is 15 units. I hope this explanation was thorough and answered all of your questions. If you have additional questions, don't hesitate to reach out! Learn on :)
