Answer: √72 or 8.49 units when rounded to the nearest hundredth.
Explanation: Because we have the endpoints if a segment and want to find the length of the entire segment, we need the distance formula.
Its general equation is √(x2-x1)+(y2-y1)
Substituting gives us √(-1-5)^2+(-9-(-3)^2
Simplifying gives us √36+36 which is √72
Also this is just a simple thing that some people forget: When you have parentheses, the exponent is distributed to everything inside including the negative. This is why we did not have a negative answer like -36 after simplifying.
