Answer: 1 unit
Step-by-step explanation:
The formula for calculating the distance between two points is given as :
D = [tex]\sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}[/tex]
[tex]x_{1}[/tex] = - 7
[tex]x_{1}[/tex] = - 7
[tex]y_{1}[/tex] = 7
[tex]y_{2}[/tex] = 8
substituting into the formula , we have
[tex]\sqrt{(-7-(-7))^{2}+ (8-7)^{2}}[/tex]
D = [tex]\sqrt{1}[/tex]
D = 1 unit
