The formula for determining the distance between two points is expressed as
[tex]\text{Distance = }\sqrt[]{(x2-x1)^2+(y2-y1)^2}[/tex]From the information given,
x1 = - 4, x2 = 8
y1 = 3, y2 = 12
Therefore,
[tex]\begin{gathered} \text{Distance = }\sqrt[]{(8--4)^2+(12-3)^2} \\ \text{Distance = }\sqrt[]{12^2+9^2} \\ \text{Distance = }\sqrt[]{225} \\ \text{Distance = 15} \end{gathered}[/tex]The distance is 15
