What is the length of this line? 30 POINTS!!

Answer:
61
Step-by-step explanation:
The first thing that you want to do is distance formula
[tex]d=(x_{2}-x_{1} )^{2} + (y_{2}-y_{1} )^{2}[/tex]
I'm going to make the start of the line at (1,1) and that means that the end of the line is at (7,6). Now, you plug these numbers into the formula.
[tex]d=(7-1 )^{2} + (6-1 )^{2}[/tex]
Then you slove
[tex]d=(6 )^{2} + (5 )^{2[/tex]
[tex]d=36 + 25[/tex]
[tex]d=61[/tex]
Distance formula: d =√(x2-x1^2 +y2-y1^2)
Find the points of the line: (2,2) and (8, 7)
Length = √((8-2)^2 + (7-2)^2)
Length = √(6^2 + 5^2)
Length = √(36+25)
Length = √61 ( exact answer) or as a decimal: 7.81
