Answer:
Explanation:
If line segments PQ has endpoints at P(-5, 4) and Q(7, -5).
To determine the length of the line, we use the distance formula:
[tex]\begin{gathered} Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \text{Where:} \\ $\mleft(x_1,y_1\mright)=P\mleft(-5,4\mright)$ \\ (x_2,y_2)=Q\mleft(7,-5\mright). \end{gathered}[/tex]Substituting the given values, we have:
