Answer

The distance between the two given points is $\sqrt{26}$ units.

Work Step by Step

Use the distance formula $d=\sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}$ where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the two given points to obtain: $d=\sqrt{((-4-1)^2+(2-3)^2} \\d=\sqrt{(-5)^2+(-1)^2} \\d=\sqrt{25+1} \\d=\sqrt{26}$
