Question

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

Answer 1

61

Explanation:

The first thing that you want to do is distance formula

`d=(x_(2)-x_(1) )^(2) + (y_(2)-y_(1) )^(2)`

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.

`d=(7-1 )^(2) + (6-1 )^(2)`

Then you slove

`d=(6 )^(2) + (5 )^{2`

`d=36 + 25`

`d=61`

Answer 2

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
