To solve this problem, we need to use the distance formula.
Distance = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
x1 = -9
x2 = 2
y1 = -7
y2 = -6
Plug your numbers in
Distance = [tex]\sqrt{((2) - (-9))^2 + ((-6) - (-7))^2}[/tex]. Simplify each parenthesis.
Distance = [tex]\sqrt{121 + 1}[/tex]. Add these numbers together and take the square root.
Distance = √(122) or 11.05 units.
