Distance formula: (D = Distance)
D = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^2 }[/tex]
Now replace each variable
D = [tex]\sqrt{[(4-(-4)]^2 + (0-7)^2}[/tex] The 4-(-4) would simplify to 0
D = [tex]\sqrt{(0)^2 + (-7)^2}[/tex] Further simplify
D = [tex]\sqrt{49}[/tex]
D = 7, -7 Distance can't be negative
Thus, D = 7
