HELP MEEEEE PLEASEEEEEE

Answer:
8.6
Step-by-step explanation:
There is an easier way which is finding the slope of the equation but I'm going to stick to distance formula(which is easier for me).
For this, you would have to know the distance formula which is
d=√(x2−x1)^2+(y2−y1)^2
Which simplifies into [tex]\sqrt{(7)^2 +(5)^2}[/tex] which you get from 6-(-1) and -2-(-7)
Further simplifies into [tex]\sqrt{49+25}[/tex]
=[tex]\sqrt{74}[/tex]
=8.602325
use the distance formula:
√ ( x2 - x1 )² + ( y2 - y1 )²
√ ( 6 - ( - 1 ) )² + ( - 2 - ( - 7 ) )²
√ ( 7 )² + ( 5 )²
√ 49 +25
√ 74
8.602325267
8.6 is the answer
