Answer:
The distance between two points
d = [tex]\sqrt{289}[/tex] = 17
Step-by-step explanation:
Explanation:-
Given points are ( 7,-1) and (-8,-9)
The distance between the two points
d = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2} - y_{1} )^{2} }[/tex]
d = [tex]\sqrt{(( (-8- 7 )^{2}+(-9-(-1))^{2} ) }[/tex]
[tex]d = \sqrt{(( (-15 )^{2}+(-8)^{2} ) }\\d = \sqrt{225+64}[/tex]
d = [tex]\sqrt{289}[/tex]
d = 17
The distance between two points
d = 17
