Question

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

Answer 1

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

Answer 2

Answer:

61

Step-by-step 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

$d=(6 )^{2} + (5 )^{2$

$d=36 + 25$

$d=61$
