Formula for the Distance between 2 points is √(x₂-x₁)²+(y₂-y₁)²
So the given points are (0,5) 0 is x₁ and 5 is y1
in the 2nd given points (-5,0) -5 is x₂ and 0 is y₂
Now we know what order the points go in so we place them into the formula which you have the following: √(-5-0)²+(0-5)²
Next we work what is in the parentheses first
√(-5)²+(-5)² now we work with exponents √25+25 next we add what's inside the square root symbol √50 the square root of 50 on the calculator gives an answer of 7.07107
