Answer:
d = sqrt{153}
Step-by-step explanation:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = distance\\(x_1, y_1) = coordinates of the first point\\(x_2, y_2) = coordinates of the second point[/tex]
Your two points are (1, -19) and (-2, -7).
[tex]d = \sqrt{-2 - 1)^2 + (-7--19)^2}\\d = \sqrt{(-3)^2 + (-7+19)^2}\\d = \sqrt{(-3)^2 + (12)^2}\\d = \sqrt{9 + 144}\\d = \sqrt{153}[/tex]
