I dont know what to do lol

Answer:
15 units
Step-by-step explanation:
The distance between two points can be found using the following formula:
[tex]d\sf=\sqrt{(x_2-x_1)+(y_2-y_1)}[/tex]
Given points:
(-7, 5) and (2, -7)
where:
Substitute these points into the formula and simplify:
[tex]\sf d=\sqrt{(2-(-7))^2+((-7)-5)^2} \ \textsf{[simplify the radicand]}\\\\ d=\sqrt{(2+7)^2+(-12)^2} \ \textsf{[simplify]}\\\\d=\sqrt{(9)^2+(-12)^2} \ \textsf{[evaluate the power]}\\\\d=\sqrt{81+144} \ \textsf{[add]}\\\\d=\sqrt{225}\ \textsf{[simplify]}\\\\d=15[/tex]
The distance between the two points is 15 units.
