Answer:
D = 4
Step-by-step explanation:
The distance between 2 points can be determined by the formula:
[tex]D = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2}[/tex]
We know that x1 and y1 are -5 and 4 respectively, and that x2 and y2 are -1 and 4, respectively.
[tex]D = \sqrt{(4-4)^2 + (-1-(-5))^2}[/tex] (Simplify)
[tex]D = \sqrt{(0)^2 + (-1+5)^2}\\D = \sqrt{4^2}\\D = \sqrt{16}\\D = 4[/tex]
