The distance between the points (5, -5) and (-7,4) = 15 units
Explanations:The task is to find the distance between two points (5, -5) and (-7. 4)
The distance, D, between two points is given by the formula:
[tex]D\text{ = }\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]In the points (5, -5) and (-7. 4) given:
x₁ = 5, x₂ = -7, y₁ = -5, y₂ = 4
Substituting the values of these coordinates into the given equation:
[tex]\begin{gathered} D\text{ = }\sqrt[]{(-7-5)^2+(4-(-5))^2} \\ D\text{ = }\sqrt[]{(-12)^2+(9)^2} \\ D\text{ = }\sqrt[]{144+81} \\ D\text{ = }\sqrt[]{225} \\ D\text{ = 15} \end{gathered}[/tex]
