Im not sure how to find the distance between the points.

Given,
the coordinates of the point is P(-4, -1) and N(1, -8).
Required
The distance between the point P and N.
The distance between the point P and N.
[tex]\begin{gathered} Distance=\sqrt{(1-(-4))^2+(-1-(-8))^2} \\ =\sqrt{5^2+(7)^2} \\ =\sqrt{25+49} \\ =\sqrt{74} \end{gathered}[/tex]Hence, the distance between the points is sqrt(74).
